In the last few years, numerous New Jersey municipalities have passed local laws governing paid sick leave, including East Orange, Jersey City, Montclair, Newark, Paterson, Plainfield, and Trenton. This patchwork of local laws left employers and workers alike confused about what was required of businesses and unsure of how to calculate and use leave. Many of these problems will be resolved when New Jersey Paid Sick Leave Act (the “Act”), which was signed into law on May 2, 2018, goes into effect on October 29, 2018 and preempts all existing New Jersey municipal earned sick leave laws.
