The UK long-term care workforce has endured difficult working conditions for many years. During the pandemic, the sector faced unprecedented challenges, which further exacerbated these conditions and brought concerns about workplace abuse and violence. Such experiences can vary by personal and work characteristics, particularly affecting minority ethnic groups. They can subsequently impact workers’ wellbeing and the sector overall. Drawing on the first wave of a UK longitudinal workforce survey, this article examined the impact of COVID-19 on social care workers’ working conditions, general health and wellbeing, and intentions to leave the employer and sector altogether. The analysis is based on both quantitative and qualitative responses 1037 valid responses received between April and June 2021. The respondents were predominantly female, working in direct care roles and mainly serving older adults (including those with dementia). The findings highlighted worrying experiences of abuse in relation to COVID-19, which differed significantly by nationality, ethnicity and care settings. The analysis further showcased the negative impact of experienced abuse on work-life balance and intentions to leave the current employer or the care sector altogether. The findings emphasise the need for targeted measures that promote workers’ physical, emotional and financial wellbeing.
