In a recent study published in the American Journal of Preventive Medicine, researchers observed lower death rates amongst workers when employers were required by law to provide paid sick leave benefits. However, the U.S. is currently one of the only developed nations without national paid sick leave legislation to protect workers. As such, this data has potential implications regarding the state preemptive laws that prevent many local governments from enacting minimum paid sick leave policies.
