Health Factors  
Community in Action

Paid sick leave laws require employers in the affected jurisdictions to provide paid time off to employees for use when ill or injured. Sick employees may use the time to see a health care provider or stay home until they are healthy enough to work again, without concern for lost wages. As of 2019, the US Bureau of Labor Statistics estimates that 24% of civilian workers in the US do not have paid sick leave1. Women, Hispanics, low-wage workers, and employees with lower levels of education are less likely to have paid sick leave than their counterparts2, 3, 4. Individuals with paid sick leave also tend to have higher incomes5, 6, 7 while those without it are more likely to have income below the poverty line8 and receive safety net services9. Some local governments cannot enact paid sick leave measures due to state preemption legislation10.

Expected Beneficial Outcomes (Rated)

  • Increased access to paid leave

  • Increased access to health care

Other Potential Beneficial Outcomes

  • Improved health outcomes

  • Increased use of parental leave

Evidence of Effectiveness

There is some evidence that paid sick leave laws increase access to paid sick leave (PSL)11, 12, 13, especially among women without a college education and workers in industries which have historically lacked access11. Access to paid sick leave can increase use of preventive health care services5, 14, 15, 16, 17, 18, 19, 20, 21. However, additional evidence is needed to confirm effects.

Access to paid sick leave can increase use of outpatient preventive care services including cancer and other health care screenings16, 18, flu vaccinations17, 21, and dental care16, as well as decrease emergency room use for children17 and adults14, 22. Workers who receive six days or more of PSL may be more likely to use preventive care services than those with two days or less, and those with ten or more days may be even more likely to15. Parental access to paid sick leave improves children’s access to health care17. Lack of access to paid sick leave appears to lead to lower levels of preventive health care use, including screenings3, 19, and delayed or forgone medical care3, 20, particularly among those with very low incomes20. Workers without access to PSL are more likely to report being in fair or poor health23, may be less able to afford needed health care services and goods (such as dental care and eyeglasses), and are more likely to incur elevated medical expenses8. Lack of PSL is also associated with increased psychological distress24 and financial worry25, while access to paid sick leave is associated with reduced financial hardship and improved quality of life26.

Access to paid sick leave is associated with an increased likelihood that employees stay home when they are ill or injured11, 27, 28, and to care for children who are ill or injured28, particularly among low income parents6. When workers gain access to paid sick leave, flu rates decrease approximately 10%, likely due to fewer employees coming to work while contagious29; PSL mandates in Connecticut and Washington, DC appeared to decrease illness-related leave taking by all workers, not just those directly affected by the change30. Lack of access to paid sick leave may increase the risk of illness for individuals and the spread of contagious illness among the wider population31.

Paid sick leave is associated with a decreased risk of mortality from all causes, particularly from heart disease and unintentional injuries32. Access to PSL is also associated with a decrease in nonfatal occupational injuries among private sector workers, particularly in high risk sectors and occupations33. For example, three years after implementation of Connecticut’s PSL law, occupational injuries and illnesses declined in the industries targeted by the law34.

A study of nine city- and four state-level PSL mandates, generally allowing workers to earn one hour of PSL per work week and up to seven days per year, suggest such laws do not significantly affect employment or wages35, while an initial assessment of Connecticut’s paid sick leave law suggests potential for small decreases in employment concentrated among older workers36. Access to paid sick leave may increase job stability for employees37 and may lead to positive effects for employers such as decreased turnover, increased productivity, and increased employee loyalty and morale4. An early study of Seattle’s Paid Sick and Safe Time Ordinance showed modest and smaller than anticipated costs to organizations following implementation38. Following implementation of the law, employer-offered leave increased in Seattle for both full and part-time employees, particularly in the hospitality sector12.

Early assessments of San Francisco’s paid sick leave ordinance suggest variable effects on profits13, 39, and some adjustments to employee benefit packages among employers who had not previously offered paid sick leave, along with some initial challenges in implementation13. One study indicates that six months after the implementation of New York City’s PSL law, workers with part-time jobs and workers without a college degree were least likely to be paid for sick days, least likely to access the benefit, and most likely to work while sick; over 1/3 of those not paid for sick leave worked in retail, food service, or health care40.

Available cost benefit analyses from advocacy organizations suggest that benefits outweigh the costs associated with PSL provision4, 41.

Responses to the Harvard School of Public Health’s 2006 Pandemic Influenza Survey suggest workers without PSL are more likely to believe they would lose their jobs or businesses if forced not to work for 7-10 days; lack of paid sick leave, inability to work remotely, and lower income levels are all associated with perceived ability to comply with stay at home orders during illness outbreaks42.

Impact on Disparities

Likely to decrease disparities

Implementation Examples

As of May 2020, 14 states and 38 municipalities including Washington, DC have enacted paid sick leave laws and ordinances43. State legislation pre-empts local laws related to leave in 22 states10. The federal Healthy Families Act, which would allow all employed Americans to earn paid sick leave, has been proposed on multiple occasions but has not been enacted.

California, Rhode Island, New Jersey, and New York have state-run public programs providing paid family or medical leave, while Washington State and Washington, DC have passed legislation2.
