On Sunday, Amazon sent notice to its workers that they would be rolling back their mask mandate for warehouse workers. Starting tomorrow, regardless of vaccination status, face masks will be optional for all workers at Amazon U.S. operation facilities. The company says they strongly recommend that unvaccinated employees continue wearing a mask and that any worker can continue to wear a mask if they feel more comfortable doing so.
