An analysis by the Institute for Women’s Policy Research (IWPR) reveals that about 25,310 or 51 percent of private sector employees in Eugene, Oregon lack even a single earned sick day off. Access to earned sick days promotes healthy work environments by reducing the spread of illness, increasing productivity, and supporting work and family balance. Earned sick days allow people to take time off work to recover from illness and to tend to family members’ health without the fear of lost pay or other negative consequences. This briefing paper presents estimates of lack of earned sick days access rates in Eugene, Oregon by sex, and personal annual earnings, and in Oregon by race and ethnicity through analysis of government data sources, including the National Health Interview Survey (NHIS) and the American Community Survey (ACS).
