Do your facilities have minimum requirements for Per Diem employees? If so, are they enforced?
Several nurses quit my last job, but stayed Per Diem, including me. The department is short staffed and the new manager has taken to sending out heavy handed emails about lots of things. The latest was to us Per Diem's, telling us she needs us to pitch in more, that she was going easy but that official policy calls for us to work one holiday a year and one weekend a month.
Well, I only want to work a couple shifts a month there. I have another job so have a weekend obligation already. I did pick up one more shift, but I've decided not to let myself be pressured like that again. I talked to one of the other Per Diem's, he was similarly turned off by the manager's approach.
