"Unpredictability is a distinctive dimension of working time that has been examined primarily in the context of unplanned overtime and in male-dominated occupations. The authors assess the extent to which female employees in low-skilled retail jobs whose work schedules are unpredictable report greater work–life conflict than do their counterparts with more predictable work schedules and whether employee input into work schedules reduces work–life conflict. Data include measures from employee surveys and firm records for a sample of hourly female workers employed across 21 stores of a U.S. women's apparel retailer. Results demonstrate that, independent of other dimensions of nonstandard work hours, unpredictability is positively associated with three outcomes: general work–life conflict, time-based conflict, and strain-based conflict as measured by perceived employee stress. Employee input into work schedules is negatively related to these outcomes. Little evidence was found that schedule input moderates the association between unpredictable working time and work–life conflict. "
