Working at McDonald's at the time. The HR manager went on bereavement leave and a replacement was brought in. The day the HR manager came back she was told she was demoted and was put as the DriveThru order taker for a couple months before finally being fired and given severance.

A month or 2 later the old restaurant manager who was now the "Systems Manager" and in charge of all the admin tasks stopped doing unpaid overtime, so all of his duties were taken away and he was put as DriveThru order taker.
For 3 months he came in for exactly 8 hours every day, only did order taking in DT, and left. He was still being paid his restaurant manager's salary during this time, the new restaurant manager was in over his head and would not ask the old restaurant manager for help. Eventually the old RM left to work for a competitor working with the old HR manager.
Apparently the owner called the competitor to scream at them for stealing his staff
