The purpose of this paper is to examine the associations between casualized employment and turnover intention in home care. Casualized employment refers to employment conditions of non-permanent contracts, part-time or casual hours, involuntary hours, on-call work, split shifts, pay per visit, and hourly pay with variable hours. Casualized employment also refers to perceived employment insecurity and labour market insecurity. Data are from a survey of 991 visiting nurses, therapists and home support workers in a medium-sized city in Ontario, Canada. Results show that, controlling for many other factors, casual hours and perceived employment insecurity and labour market insecurity are positively and on-call work is negatively associated with home care workers' turnover intention. Non-permanent contract, part-time hours, involuntary hours, split shifts, and non-salaried pay are features of the market-modelled home care work environment and therefore may not be associated with turnover intention. Results provide evidence on the effects of casualized employment strategies on home care workers' turnover intention.
