Migrant Home Care Workers in the UK: a Scoping Review of Outcomes and Sustainability and Implications in the Context of Brexit.

Migrant care workers play a significant role in meeting the escalating demand for social care in the UK. Workforce shortages create opportunities for new migrants to enter the social care workforce. This scoping review aims to identify and synthesise available evidence on the contribution of migrant workers to the provision of home care in the UK focusing on care worker and service outcomes as well as sustainability, and identify challenges and gaps in the context of Brexit and changing immigration policies. Twenty-two articles were identified for inclusion in the review and extracted using a structured format. The analysis presents a narrative description and synthesis of the research. Findings from the reviewed articles were grouped into five main themes: migrant, user and employer outcomes, effect on workforce, and sustainability-and 15 sub-themes that were described in detail. Much of the existing research on migrant care work is qualitative and focuses on migrant outcomes. The review identified some important gaps in research, namely, the impact of immigration status on migrant care worker outcomes, the cultural and psychological adaptation of migrant care workers to care practices, and the emerging UK live-in care market. Implications of findings are discussed in the context of post-Brexit immigration system.

Background

Migrant workers are increasingly filling labour gaps in long-term care across the world, driven by demographic changes and responding to major challenges in the delivery and cost of care (Anderson, 2012). Although migrant care workers are present in most countries, their share and roles vary significantly and are affected by different factors. Major among these are the welfare state and immigration regimes of host countries (van Hooren, 2012). Demand for migrant care workers is shaped by the institutional structure and specific configurations of the social care system (Anttonen et al., 2003, p. 13; Simonazzi, 2008; Lyon & Glucksmann, 2008). Williams (2012) argues that variations in the employment of migrant care workers are influenced by how employment, migration, and social care systems interact. These systems alone and in interaction also create or contribute to the vulnerability of migrant care workers.

The UK is similar to many European Union (EU) and OECD countries in that it relies heavily on migrant care workers, who are over-represented in the long-term care sector (Cangiano, 2014). In 2020 (prior to the COVID-19 pandemic), non-UK nationals represented 17 per cent of the social care workforce in England (Skills for Care, 2020), compared to approximately 11 per cent of all people in employment (ONS EMP06).

In 2016, the UK voted to leave the EU and as part of the Brexit process, to ‘take back control’ of its borders and ‘end free movement and the preferential treatment’ of EU migrants.1 The Brexit decision was followed by years of political uncertainty about the shape and nature the UK’s future relationship with the EU. In 2020, the UK left the EU with a transition period until the end of the year. Following its election manifesto in 2019 (Conservative and Unionist Party, 2019, p. 20), the government will introduce a new immigration system in 2021 that ends rights to free movement for EU workers and implements a points-based immigration system for everyone moving to the UK for work (Home Office, 2020).

Under the new immigration system, few—if any—care worker jobs will allow applicants to collect the required number of points to qualify for a work visa: the majority of positions in social care are below the minimum qualification level. The impact of the new rules on social care are not yet evident, however are likely to be significant in the broader context of high vacancies and turnover in the sector and pressures created by the COVID-19 pandemic (Dromey & Hochlaf, 2018; MAC 2018; Morris, 2020; Skills for Care, 2020).

The aim of this review is to scope and present the available research on the migrant care workforce in one of the segments of the UK social care sector—home care. The analysis will focus on key worker and user outcomes and contribute to the assessment of challenges in the context of Brexit and changing immigration rules.

Social Care in the UK

Social care in the UK covers personal care and practical support for people who need care and support due to disability, illness, old age, and their carers (NAO, 2018). The two main components are residential care (i.e. care homes and nursing homes) and domiciliary care (care and support provided in one’s home). Social care is a devolved responsibility of the four national governments—England, Scotland, Wales, and Northern Ireland (NI)—that have taken diverging policy directions with funding and individual outcomes (wellbeing) at the centre of reforms over recent decades (Hall et al., 2020).

Pressures on workers’ wages and rights have had a negative effect on the sector’s ability to attract or retain workers (Hudson, 2019). Vacancy and turnover rates have been persistently high (Hussein et al., 2016).

These trends have been set in a broader context of ‘personalisation’ and ‘consumer choice’ primarily delivered via cash for care policies (such as personal budgets and direct payments) in quasi-markets of suppliers of care services (Needham, 2011; Owens et al., 2017). Marketisation and personalisation have created a complex and fragmented landscape of services, particularly in England, where there were 18,200 organisations and 38,000 establishments (e.g. care homes) involved in the provision of adult social care in 2019/2020, ranging from micro-providers to large corporate chains (Skills for Care, 2020). While the majority of social care services are publicly funded and purchased by local authorities via competitive tendering, it is estimated that approximately 35–40% of service users self-fund their own care by sourcing services from an open market (Hall et al., 2020).

Domiciliary or home care represents nearly half of social care jobs and workforce, and it has some distinct features:

High number of ‘direct care’ jobs and fewer roles requiring formal qualifications. Over half of the domiciliary care workforce in England have no care related qualifications (higher than any other social care sector).

Insecure and precarious employment practices: Nearly half of the home care workforce in England are on a zero-hour contract, highest rate within the social care sector. Zero-hour contracts are a source of additional stress for home care workers (Ravalier et al., 2019).

Highest vacancy and turnover rates within the sector. In England, the vacancy rate in domiciliary care was 10% in 2018/2019 compared to 7.8% for the sector as a whole or 5.9% in residential care.

Live-in care is a small but significant segment of the home care market in the UK. It relies heavily on migrant care workers, often recruited directly from abroad.

Home care workers are significantly more likely to experience ‘high strain’ jobs than their colleagues working in residential care (Hussein, 2018).

Care is delivered in clients’ homes, and home care workers often work alone and thus have less organisational and peer support than those working in residential settings. The relational aspects of home care are also different from institutional forms of care (Denton et al., 2002).

The rapid spread of “disruptive technologies” such as introductory agencies and “uber-style” technology platforms that connect people who use services directly to those who provide them and its implications for worker and user rights and liability (Bolton & Townson, 2018).

Social Care Workforce and Migrant Care Workers

The social care workforce is predominantly female (over 80% in England and Scotland) and one of the lowest paid in the UK economy with average pay close to the statutory minimum wage (Skills for Care, 2020). Non-UK nationals make up 17 per cent of the social care workforce as a whole and 15 per cent of the home care workforce in England (no data are available for the other UK nations), with very little change since 2012 (Skills for Care, 2020).

Migrant workers have traditionally contributed significantly to health and social care in the UK (Simpson et al., 2010). The share of EU migrants working in social care has increased since the accession of new Member States from Eastern Europe in 2004 and 2007 and the 2008 immigration reform that introduced restrictions on the direct recruitment of non-EEA workers to ‘low-skilled’ occupations. Currently eight per cent of non-British care workers are EEA, and nine per cent are non-EEA nationals, with significant regional variation (Skills for Care 2019). In 2017, the UK was the second largest destination of ‘mobile personal care workers’ within the EU, receiving a fifth of the intra-EU mobility (Fries-Tersch et al., 2018). By 2018, Romanian and Polish nationals were the two largest groups of workers in social care, followed by nationals from the Philippines, Nigeria, India, and Zimbabwe (Skills for Care 2019). Thus, migrants constitute a significant part of the formal care workforce and offer an additional recruitment pool from which providers in the sector have been filling labour gaps (Cangiano, 2014).

Reliance on migrant workers in the UK is among the highest in the EU, and it has been referred to as ‘a structural feature of the [UK] care sector’ (Cangiano et al., 2009; p. 163). This has also been described as the ‘migrant in the market’ model, where reliance on migrant workers is largely attributed to their willingness to accept—at least temporarily—the low pay and difficult working conditions characteristic of a privatised and residual social care system in exchange for a relatively easy entry to the local labour market (van Hooren, 2012; da Roit & Weicht, 2013). All else being equal, non-UK nationals were more likely to leave a social care job than their British national colleagues (Vadean et al. forthcoming). An important feature of the UK migrant care workforce, currently, is that the majority are recruited locally and have unrestricted right to work in the country (Cangiano et al., 2009, p. 66-67), and they participate in formalised care provision and labour market.

Aims and Review Questions

This scoping review is part of a larger study investigating migrant labour in the UK home care sector. The review undertaken aimed to take stock of available evidence on the contribution of migrant workers to the provision of home care in the UK and contribute to the assessment of challenges in the context of Brexit and changing immigration rules. In particular, the review set out to examine the following questions:

What are the experiences of migrant care workers in the UK (migrant outcomes)? What is known about the wellbeing of migrant care workers?

What drives the recruitment of migrant care workers and what are the actual and perceived benefits of employing them from the perspective of employers (employer outcomes)?

What are the experiences of care users in relation to home care provided by migrant workers (service user outcomes)?

What is the impact of migrant workers on the workforce as a whole (workforce outcomes)?

What is known about the sustainability of supply and demand for migrant care workers (sustainability)?

Methods

The review used systematic searches and developed a narrative synthesis of the literature.

Studies that comment on any type or aspect of home care provided by migrant care workers in the UK, including comparative studies, were considered for inclusion in the review. Given our focus on current patterns and challenges in the context of Brexit—the end of free movement—only literature published between 2004 and 2019 were included. The year was selected to coincide with the EU’s first Eastward enlargement and the opening up of the labour market to a large number of workers from the new member states (Pollard et al., 2008).

Peer-reviewed publications, PhD dissertations, and reports published as grey literature were eligible for inclusion if they included some empirical analysis of primary or secondary data. Non-empirical studies (e.g. commentaries) and books were excluded. Systematic reviews were screened for potentially eligible studies. Only research published in English was included in the review.

Eight electronic databases were searched using both free text and keyword terms combined with Boolean operators AND and OR (see Table 1). No geographical filters were used to ensure that UK literature was fully captured in the search results. Language and publication date filters were applied to search results.

Titles and abstracts of studies identified through electronic searching were screened against the eligibility criteria by AT, and decisions were reviewed by SH. Original searches were conducted in May–June 2018 and updated in May 2019 and August 2020, and this resulted in no further studies.

A form (in Microsoft Excel) with the following categories was used to extract information from the studies: study aims, review themes, participants, methods, theoretical framework, findings, implications for Brexit, and limitations.

The quality of studies was not assessed in a formal way, and no papers were excluded from the analysis on the basis of risk of bias (Arksey & O’Malley, 2005). However, in the process of data extraction, limitations and potential sources of bias were noted for each paper. The quality of research and the limitations of the evidence base are discussed in more detail in the findings section.

The analysis presents a narrative description and synthesis of the existing literature using the review questions as a conceptual framework. Studies were coded according to their relevance to each of the key topics of the review (i.e. review questions), and data was extracted into the template. This was then analysed using a framework approach (Thomas et al., 2012; pp. 191-93).

Results

Search Results

The search of electronic databases yielded 4274 titles, before removal of duplicates across databases. After the removal of duplicates, initial screening, and application of eligibility criteria based on the abstract, 49 papers were marked as potentially relevant (Fig. 1). If a study was available as both a report and a peer-reviewed publication, only the published peer-reviewed paper was included in the review.

Prisma flow chart

Of the 49 studies retrieved, 28 were excluded due to eligibility: lack of empirical analysis or non-UK focus. This left 21 studies for full-text screening and data extraction. At this stage, another study was excluded because it did not include any home care workers, and two further papers were identified through citation tracking. This resulted in a total of 22 studies included in the review (Table 2).

Description of the Literature

The 22 papers in the review came from a total of seven studies. Four studies contributed more than one publication:

International social care workers: initial outcomes, workforce experiences, and future expectations, 2007-10 (NIHR-CCF 056/0013) (Hussein, Manthorpe, Stevens)

Longitudinal Care Work Study, 2009-18 (DH/035/0095) (Hussein, Manthorpe, Stevens, Moriarty)

The Role of Migrant Care Workers in Ageing Societies, 2007-09 (The Atlantic Philanthropies and Nuffield Foundation) (Shutes, Walsh, Cangiano)

Welfare policy and care work. A cross-national Norwegian / UK social study of migrants in care work, 2011-12, (Meltzer Foundation, Norway) (Christensen, Manthorpe, Hussein)

Only three papers focused specifically on home care (Datta et al., 2010; Christensen & Manthorpe, 2016; Christensen, 2017). The others included both home and residential care, and one also included social workers. Two studies (McGregor, 2007; Datta et al., 2010) focused on migrants from a specific region (Africa); Hussein et al. (2011a) considered the experiences of care workers who came to the UK as refugees and asylum seekers, and one paper (Read & Fenge, 2019) explored the perspectives of employers on workforce challenges associated with Brexit. All other papers had a broad focus on migrants from any countries, although some commented on similarities and differences between various groups (e.g. EEA, Commonwealth, and non-EEA).

Most papers (n=13) were qualitative; there was one quantitative analysis, and eight studies adopted a mixed methods approach combining survey/secondary analysis with qualitative methods.

Most papers addressed more than one topic, and the highest number of studies contributed to the questions of migrant care worker (MCW) outcomes (n = 12) and sustainability (n = 9), while relatively few studies explored employer (n = 4), workforce (n = 3), or service user outcomes (n = 3) (Fig. 2). The characteristics of studies are summarised in Table 2.

Themes identified in the literature

Synthesis of the Literature

Migrant Care Worker Outcomes

Four themes were identified in relation to migrant care worker outcomes: migrant agency, migrant experience, risks and vulnerabilities, and relationships and values in care.

The relevance of ‘migrant agency’ is highlighted in several papers (Christensen, 2017; Christensen et al., 2017; Hussein et al., 2013). The decision to move to the UK and taking up employment in social care are separate steps in the migration trajectory. The UK is often chosen as a direct destination (Christensen, 2017), and the status of the English language as an ‘exportable asset’ potentially facilitates short-term and temporary migration (Christensen et al., 2017). The decision to work in social care is often pragmatic and instrumental (Hussein et al., 2011b). Although migrants recognise the disadvantages of working in social care—low pay, low status, and precarious conditions—they also see it as a stepping stone towards other jobs in the sector or beyond. Researching the Zimbabwean community in the UK, McGregor (2007) shows how becoming a care worker is part of the arrival narrative, and although entry to care often occurs for pragmatic reasons, a number of positive comparisons are made with other sectors that employ large numbers of migrants (such as construction).

Migrant care workers represent a very diverse group in the UK. Christensen et al. (2017) found no dominant settlement tradition in life stories of migrant care workers: some settle and acquire British citizenship but maintain a strong sense of belonging, while others return or move to other countries.

Crossing more traditional gender divisions of labour is another aspect of migrant agency. Migrant men are overrepresented in care work, and their entry and settlement dynamics are also distinct from those of women. Hussein and Christensen (2017) identify three such dynamics: ‘stumbling upon care work’; negotiating a ‘trapdoor’ of gendered expectations to gain access to the sector; and developing compensating perspectives, including material and relational justifications and positive male roles.

The second theme, ‘the migrant experience’, refers to a range of lived experiences associated with being a migrant, first and foremost. Migrant care workers often describe themselves in interviews as ‘resilient’, ‘committed’, or ‘determined’ and view these characteristics as assets and a positive contribution to social care (Hussein et al., 2011b). These characteristics are also evoked to cope with negative experiences many migrant care workers encounter. Discrimination, racism, and unfair treatment were often mentioned in the reviewed literature, especially for non-white migrant care workers (Hussein et al., 2011a, 2011b; Shutes & Walsh, 2012; Datta et al., 2010; McGregor, 2007; Stevens et al., 2012; Walsh & Shutes, 2013). Racism, however, is not necessarily open and direct; it is often expressed through cultural and linguistic ‘grievances’ as well as racialised assumptions/expectations about competence and character (Walsh & Shutes, 2013). Support from management and co-workers is crucial, but not always offered in the context of personalisation and user choice, where migrant care workers are often expected to tolerate racism, particularly from people seen as ‘vulnerable’ (Shutes & Walsh, 2012; Stevens et al., 2012). Many migrant care workers are part of global care chains, with families left behind and/or a lack of familial networks in the UK. In the context of restrictive migration policies, family expectations and managing their own caring arrangements can put pressure on migrants and increase their vulnerability to exploitation or limit their opportunities for advancement (Datta et al., 2010; McGregor, 2007).

The third theme ‘risks and vulnerabilities’ highlights that migrant care workers are more vulnerable to risks created by the structural combination of personalisation and care work organisation. These include precarity, isolation, emotional challenges, gendered risks of abuse, and unfair treatment (Shutes, 2012; Shutes & Walsh, 2012; Christensen & Manthorpe, 2016). The nature of home care, particularly the blurring between private and public, employer, and client aspects, can further complicate this problem in the context of a marketised system (Shutes & Walsh, 2012).

The fourth theme to emerge from this review is ‘relationships and values in care’. This is about how migrants see their role and contribution to social care. Several studies highlight that working in care—despite all the difficulties—is a valued experience for many migrant care workers and find that relationships with clients are a core determinant of positive outcomes (McGregor, 2007; Hussein et al., 2013). Relational aspects of care are seen as particularly important in home care (Walsh & Shutes, 2013), and many migrant workers construct work as ‘nurturing’ and ‘holistic’ and clients as ‘family’, placing emphasis on their own societal and cultural values, such as respect and care (McGregor, 2007; Datta et al., 2010; Hussein et al., 2013). This might result in tensions between personal values and the commodified and corporatised system of care, with implications for the emotional wellbeing of migrant care workers (Datta et al., 2010).

Service User Outcomes

Few studies explored the experiences of service users in relation to social care provided by migrant workers (Manthorpe et al., 2012a; Manthorpe et al., 2012b; Walsh & Shutes, 2013). Manthorpe et al. (2012b) identified four ‘ideal types’ in terms of satisfaction with care and preference for British care workers. While some service users voice openly racist and discriminatory views and preferences for care workers, many people are more cautious in expressing such views. Key concerns from the perspective of service users are cultural and linguistic proficiency and relationships with migrant care workers. While cultural and linguistic ‘grievances’ are often an expression of racism and discrimination, there is also evidence that a lack of cultural and linguistic proficiency—which makes communication ‘hard work’—may be associated with negative user outcomes, such as loneliness and isolation, especially for more vulnerable people (Manthorpe et al., 2012a). Characteristics associated with the ‘migrant experience’ such as resilience, commitment, and maturity, however, are often highly valued by service users and can to some extent compensate for a lack of cultural and linguistic proficiency that has the potential to improve with time and continuity (Manthorpe et al., 2012a; Walsh & Shutes, 2013).

Employer Outcomes

The three themes for employer outcomes are the following: migrant workers are a source of flexibility; impact on quality of care; and the burden of employing migrant care workers. Migrant care workers fill gaps in the supply of British-born workers and provide an important ‘source of flexibility’ for providers in three key aspects (Shutes & Chiatti, 2012): (1) migrant workers, especially initially, are more likely to accept less favourable conditions; (2) they are more ‘available’ for work (i.e. willing to work longer or unsocial hours); and (3) they are perceived to be more ‘committed’ and ‘reliable’ by their employers, most likely due to their immigration status or recent migration experience. As put by Hussein et al. (2011b), ‘the main reason why the English care sector recruits migrants is their willingness to do work that may be seen as unattractive by the local population. This appears to be more important than other attributes’ (p. 295).

The ‘burden and challenges’ theme highlights some of the difficulties associated with employing migrant workers: induction and training for new migrants; tensions arising from mediating racialised/discriminatory user preferences and workers’ rights to non-discrimination and dignity; and ‘paperwork’ (Cangiano & Shutes, 2010; Shutes & Walsh, 2012). Increasingly complex immigration rules and requirements put administrative and financial pressure on employers and create ‘risk work’ associated with ‘getting it wrong’, an issue that particularly affects smaller providers and may prevent some from employing job applicants subject to immigration control (Manthorpe et al., 2018). There are some suggestions of relatively high levels of irregular employment of migrant workers in social care (Cangiano & Shutes, 2010; Shutes, 2012); however, evidence is lacking in this area.

No studies were set out to specifically investigate the impact of employing migrant care workers on ‘quality of care’, but where this is discussed, provider organisations do not report any negative impact and some note improvements (Walsh & Shutes, 2013).

Workforce Outcomes

Only two studies commented on workforce outcomes and highlighted that migrant care workers are ‘structurally different’ from the general social care workforce. Firstly, they are ‘structurally positioned’ in low-paid and precarious jobs, especially in the private sector (Shutes & Chiatti, 2012). Secondly, recent migrant workers are more likely to be employed in ‘direct care’ roles, more likely to be working full time, and they are better qualified yet less likely to hold managerial or supervisory positions; they are younger, and a higher proportion are male compared to the social care workforce as a whole (Hussein et al., 2011c).

Sustainability

We considered the factors that would allow the supply and demand for migrant care workers to be maintained at functional (i.e. existing) levels. On the supply side, two key themes were identified. First is the ‘role of perception’ in destination country and sector choice. Migrants exercise a degree of agency in their decisions, and thus, the perceived accessibility and attraction of a country may be as important as its immigration policies (Christensen et al., 2017). Migration to the UK is aided by historical ties, existing migrant networks, and pragmatism, such as acquisition of English language. The availability of jobs in social care that do not require formal qualifications is recognised by migrants and acts as a ‘pull’ factor for those seeking to gain a foothold in the local labour market (Hussein et al., 2013).

Second, social care taps into the stock of migrants with right to work already in the country, and only a minority of migrant care workers were recruited directly from outside the UK (Cangiano & Shutes, 2010). Fluctuations and a fall in the number of migrants in the context of Brexit create uncertainties and challenges for employers particularly in home care and certain areas of the country (Read & Fenge, 2019). Although there is increased interest in employing refugees in social care, this is unlikely to be sufficient to fill gaps in workforce supply (Hussein et al., 2011a).

On the demand side, ‘structural factors’ and immigration rules shape demand for migrant workers. The relative importance of migrant care workers has increased within an expanding sector in the recent decade. Due to the uneven distribution of migrant workers, some regions and sectors are likely to be more vulnerable to a sharp drop in the supply of migrant workforce than others (Cangiano & Shutes, 2010). Demand for migrant care workers can be negatively affected by complex immigration rules and the requirement for employers to enforce immigration regulations, which can make it financially unfeasible and unsustainable for smaller employers to hire migrant workers, as highlighted by provider experiences after the 2012 visa reforms (Manthorpe et al., 2018).

One report (Independent Age, 2016) examines the combination of supply and demand side factors to estimate the workforce gap in social care by 2037. Taking the current ratio of care workers to older people taken as a baseline, it was projected that demand would outstrip the supply of social care workers, with migrant care workers needed to fill gaps. The report shows that zero net migration could leave a shortfall of up to 400,000 workers in the sector.

Discussion

Migrant care workers provide more than a flexible source of labour to fill gaps in social care provision in the UK; they contribute to the sector in several ways, as highlighted by the findings of this scoping review. There has been a significant emphasis in the reviewed literature on ‘wellbeing failures’ (McGregor, 2014) experienced by migrant care workers, as well as migrant agency and experiences. Many of the findings in the reviewed studies resonate with the international literature on migrant care workers (e.g. Doyle & Timonen, 2010; Bauer & Österle, 2013; Di Rosa et al., 2012; Da Roit & Van Bochove, 2017; Theobald, 2017).

The review identified some gaps and limitations of existing UK research, particularly in the context of Brexit and changing immigration policies. To date, there has been less focus on what fosters positive wellbeing outcomes of migrant care workers and how migrant agency is mediated by immigration status (e.g. those with full right to work and those without, EU nationals, and non-EU nationals), race, class, and gender in the UK literature (Schwiter et al., 2018; Hamilton et al., 2019).

Although cultural and linguistic ‘grievances’ as well as racialised assumptions about competence and character have been highlighted in the reviewed literature, there has been limited research on sociocultural and psychological adaptation and socialisation—whereby migrant care workers adopt the rules and patterns of the receiving country (Ho & Chiang, 2015). The outcomes of these directly influence migrant care workers’ ability to provide ‘culturally congruent’ care (p. 239), as well as psychological wellbeing, and as a result affect the quality of care provided.

Racism towards migrant workers has received some attention in the literature, but the focus to date has been on ‘visible’ minorities. Eastern European migrants, even though they are predominantly white, have been described as a ‘racialised’ minority in the UK (Fox et al., 2012, 2015). Yet, their experiences in social care are not well explored or understood, especially in the context of Brexit (Kilkey & Ryan, 2020; Sotkasiira & Gawlewicz, 2020). There is limited research on the perception and lived experiences of discrimination among migrant care workers, including employer and wage discrimination.

Few studies focused on home care or live-in care, or compared different social care sectors, even though they are associated with different risks and challenges (Charlesworth & Howe, 2018). There is limited knowledge on how demand for, recruitment, and ‘matching’ of live-in migrant care workers to the needs or preferences of older care users or their families are shaped by their (real or assumed) attributes in the context of privately purchased care and the role of labour market intermediaries (Leiber et al., 2019; van Bochove & zur Kleinsmiede, 2020).

Social care has several distinguishing features that set it apart from other low-paid sectors with a high proportion of migrants (e.g. food processing, retail, and hospitality). Van Hooren et al. (2019) highlight three points: first, “migrants directly enter the sphere of the welfare state”; second, it is a “distinctly gendered segment of labour migration, not only because many of the migrants involved are women but also because the politics of care is often strongly gendered” (see also Hayes, 2018); and third, much migrant care work “takes place within the intimate sphere of the home”, which can create a demand for undocumented migration even in countries where this is relatively limited (p. 364). The UK social care sector is already vulnerable to risks of exploitation and modern slavery due to its purchaser-provider split and the use of complex tendering (commissioning) practices with weak oversight over labour supply chains (Emberson & Trautrims, 2019). The post-Brexit immigration system—the lack of legal work migration route for care work—is likely to add to existing pressures.

Finally, there is limited information on wellbeing outcomes for people who are supported by migrant care workers, although there is some suggestion in the literature that any negative outcomes may be outweighed or overcome by positive contribution of care workers’ experience and resilience. A better understanding of this, alongside future demand from an increasingly diverse ageing population, could provide an important contribution to any discussion on the future shape of care migration.

Conclusion

In the current UK context, migrant care workers combine the risks and vulnerabilities of migrant status with the pressures of an already marginalised social care sector (Hussein, Manthorpe & Stevens 2011; Cunningham & James, 2014). With a growing and increasingly diverse ageing population, it is likely that the UK home care sector will continue to need migrant care workers to fill gaps in the workforce. The end of free movement of EEA workers and the new post-Brexit immigration system will create new risks and challenges that will be unfolding in the context of the COVID-19 pandemic. While the new immigration system is expected to reduce the labour supply by restricting migration into social care, the pandemic and its broader economic impact—the collapse of vacancies and job losses in other low-paid sectors (i.e. retail and hospitality)—has increased (at least temporarily) the labour supply in the care sector. Furthermore, the high rates of COVID-19 mortality in UK care homes (ONS, 2020a, 2020b) might turn people in need of care and support to sectors perceived as ‘safer options’, particularly live-in care that traditionally relies on migrants. Combined with the introduction of a more restrictive immigration system, this could create incentives for the emergence of an unregulated and informal ‘grey’ market of care in people’s homes.
