*NA, not applicable. †Values are percentage (no. persons worked at any location/no. persons scheduled to work). ‡p<0.001 (comparison of 3 work experience categories for specified day and period). §Values are adjusted odds ratio (95% CI). Dependent variable for the multilevel logistic regression models is worked at any location on a specified day of illness (0 = did not work, 1 = worked). Independent variables are work experience in a typical week before illness onset (remote only, hybrid, onsite only), study period (0 = prepandemic influenza seasons, 1 = COVID-19 pandemic period). PCR test result (0 = other acute respiratory illness, 1 = influenza or COVID-19), race/ethnicity, general health before illness, current smoker, type of employment, healthcare personnel, hours worked in a typical week before illness onset, employees discouraged from coming to work with flu-like symptoms, and study site. We excluded persons with missing information for independent variables (303 for day 1, 314 for day 2, and 279 for day 3). p<0.001 for work experience study period interaction term for days 1–3 of illness.
