Workplace protections are now in effect for New York City residents who also have caregiving responsibilities at home.
The law, signed by Mayor Bill de Blasio in January, took effect Wednesday.
It protects employees from termination, demotion, or denial of promotion because of their status as a family caregiver.
If the law is broken, the worker could recover lost wages or damages.
De Blasio calls family caregivers "unsung heroes."
The city's human rights commissioner, Carmelyn Malalis, says parents and people caring for sick or disabled loved ones are among the hardest workers in the city.
