This mixed-methods study identified the personal and workplace characteristics that drive the job satisfaction of home support workers (HSWs) providing assistance to elderly clients. Data were based on a standardized measure of job satisfaction, along with in-depth qualitative interviews with 176 home support workers from three Canadian provincial jurisdictions (British Columbia, n = 108; Ontario, n = 28; Nova Scotia, n = 40). We anticipated that variability in demographic profiles between the three groups of workers and different job descriptions would be associated with differences in perceived job satisfaction. This was not the case. Results from the qualitative analysis highlight key areas that contributed to job satisfaction. These are job (scheduling, travel, and safety), economic (income security), and organizational (communication, support, and respect) factors. Given these findings, we recommend improvements to workplace communication, increased travel time allowance between clients, and wage parity with equivalent positions in long-term care facilities.
