Share of workers and reported level of work stress, salaried vs. hourly worker, by shift type

Day shift
(Stress level/share)
Night shift
(Stress level/share)
Irregular shift
(Stress level/share)
All (n= 4,641)  77%  6%  16%
Salaried 3.3 (86%) 2.9 (2%) 3.3 (12%)
Hourly 3 (75%) 3(10%) 3.1(15%)
Other  3 (60%) 2.7 (3%) 3 (35%)

Note: The stress scores reflect workers' responses (1= never, 2=hardly ever, 3= sometimes, 4=often, and 5=always) to the question, "How often do you find your work stressful?" T-tests show the differences between irregular shift and day shift are not statistically significant. The “Other” category includes people working as independent contractors, independent consultants, or freelance workers. Shares shown may not add up to 100 percent due to rounding.
