Prior to 2014, there were only 4 paid sick leave laws in effect nationwide. That number has grown to more than 30 laws, covering several states, cities, and counties. The infographic below provides a broader picture of which states, cities, and counties offer paid sick leave laws.
UPDATE: The infographic below reflects the new law in Colorado. On July 14, 2020, Governor Jared Polis signed into law the Colorado Healthy Families and Workplaces Act (HFWA), which goes into effect for covered employers with 16 or more employees on January 1, 2021, and for all other covered employers (regardless of how many employees they employ) on January 1, 2022.
