This Law Firm Publication by Epstein Becker & Green, P.C. discusses the New York City Department of Consumer Affairs's (DCA) newly adopted amendment to the rules concerning the enforcement of the city's Earned Sick Time Act (Act). The amendment, which became effective on March 4, 2016, is geared towards clarifying, and guiding employers in following, the Act. The amended rules provided guidance on issues such as applying the law in the context of temporary and joint employment, determining how to calculate the number of employees within the city, recordkeeping, and retaliation. The amended rules also include requirements for employers' written sick leave policies, including how to calculate leave time, how the time may be used, and whether it can carry over to a new year.
