An analysis by the Institute for Women’s Policy Research (IWPR) finds that approximately 47 percent of private sector workers living in Oregon lack even a single paid sick day (these figures exclude workers in Portland and Eugene, which both have paid sick days ordinances). This lack of access is even more pronounced among low-income and part-time workers. Access to paid sick days promotes safe and healthy work environments by reducing the spread of illness and workplace injuries, reduces health care costs, and supports children and families by helping parents to fulfill their caregiving responsibilities. This briefing paper presents estimates of access to paid sick days in Oregon by sex, race and ethnicity, occupation, hours worked, and personal earnings through analysis of government data sources, including the 2011–2013 National Health Interview Survey (NHIS), and the 2013 American Community Survey (ACS).
