Abstract
Objectives. We compared work and lifestyle activities for workers who work in 1 job with those who work in multiple jobs during a 1-week period. Methods. We used information from the 2003–2011 American Time Use Survey to classify workers into 6 work groups based on whether they were a single (SJH) or multiple (MJH) job holder and whether they worked their primary, other, multiple, or no job on the diary day. Results. The MJHs often worked 2 part-time jobs (20%), long weekly hours (27% worked 60+ hours), and on weekends. The MJHs working multiple jobs on the diary day averaged more than 2 additional work hours (2.25 weekday, 2.75 weekend day; P < .05), odd hours (more often between 5 PM and 7 AM), with more work travel time (10 minutes weekday, 9 minutes weekend day; P< .05) and less sleep (–45 minutes weekday, –62 minutes weekend day; P< .05) and time for other household (P < .05) and leisure (P< .05) activities than SJHs. Conclusions. Because of long work hours, long daily commutes, multiple shifts, and less sleep and leisure time, MJHs may be at heightened risk of fatigue and injury.
