Thousands of Eastern Europeans find employment caring for older individuals as transmigrating live-in home care workers in private households in Germany. Studies have shown that the stressors threatening their well-being are multifaceted and include inequalities and a high practical and emotional workload, but research on protective factors is still scarce. This qualitative descriptive study focuses on both the stressors and factors that promote care workers' well-being and contribute to their psychological resilience. In guideline-based interviews, 14 female and one male care workers were asked about their stressors and the factors that help them cope. Identified stressors included separation from their own family, strained relationship with either or both the care recipient (dementia) and their relatives (violation of worker´s rights and devaluation of care work), and permanent availability and lack of free time due to a 24-h care schedule. Resilience factors were both external and internal and included positive social relationships, self-determination, experience in care work, and intrinsic job motivation. Live-ins reside in an ambiguous setting, exposed to both structural and individual strains. However, external and internal resilience factors contribute to a generally positive attitude toward their job and indicate the agency of this precariously employed group. A socially anchored appreciation of their work and an officially controlled expansion of free time are mandatory to improve the working conditions of live-in care workers.
