Pennsylvania state Rep. Seth Grove introduced legislation last month to block cities and municipalities from imposing paid sick leave requirements on businesses, even as COVID-19 cases are raging throughout his state and the country. Last week, local news media reported that the Republican lawmaker was now quarantining after exhibiting coronavirus symptoms and awaiting test results.

Grove’s preemption bill is the latest salvo in an ongoing war over stripping worker protections that continues to be fought in statehouses and Congress, even as the coronavirus pandemic spirals out of control. With Democrats in Washington preparing to drop paid sick leave from President Joe Biden’s first COVID-19 relief bill, potentially leaving eighty-seven million workers without protection, the responsibility for providing the benefit to workers now falls squarely on states — the very place the war has been waged for the last decade.

Paid sick leave statutes require businesses to provide employees with medical leave for ailments and injuries. Grove has been pushing for legislation to bar localities from imposing such requirements since 2013. His latest bill, reintroducing the measure, would be retroactive to 2015 — the year Democratic strongholds Philadelphia and Pittsburgh passed laws mandating paid sick leave.
