United Airlines has announced to their employees that they will be allowing unvaccinated employees who received an approved accommodation will return to their jobs starting March 28th. In their memo they said that about 2,200 employees had received vaccine related accommodations. The airline says they have no plans to rehire the around 200 employees who simply did not comply with the mandate and were fired.
