Law firm Littler Mendelson on Sunday released an insight on employee Covid vaccination mandates. It includes a chart on vaccination mandates issued at the federal and state levels. The insight comes amid the recent announcement by President Biden that large companies will have to ensure their workers are vaccinated or tested weekly for Covid. A number of states are also issuing mandates for healthcare workers, teachers and others. A number of private companies, including airlines, are also issuing mandates.
