Republicans want to help businesses kill workers. They want to force employees to return to Covid-19 hotspots, like slaughterhouses, by depriving them of unemployment checks if they don’t clock in. In addition, Senate Majority leader Mitch McConnell wants to give these businesses and others, like nursing homes, legal immunity for deliberately exposing workers to a deadly plague. On May 26, he announced such legislation. Make no mistake: McConnell’s liability protection is a license to kill. He’s gone from being the gravedigger of democracy to just being a gravedigger.
