A new analysis by the Institute for Women’s Policy Research (IWPR) reveals that more than 700,000 private sector employees in Maryland lack even a single earned sick day. Access to earned sick days promotes healthy work environments by reducing the spread of illnesses, , increasing productivity, and supporting work and family balance. Earned sick days allow people to take time off work to recover from personal illnesses and to tend to family members’ health without the fear of lost pay or other negative consequences. This briefing paper presents estimates of earned sick days access rates in Maryland by occupation, by sex, race and ethnicity, and personal annual earnings, through analysis of government data sources, including the 2010–2011 National Health Interview Survey (NHIS) and the 2011 American Community Survey (ACS).
