About a week ago, I called in an option day an hour and a half before my start time. The center manager asked me if I was sick and I said no. He then said I was doing this the wrong way and needed me to come into work or I would be written up the following day. I didn't come in that day and sure enough I was written up the next day. He said that option days are to be scheduled in advance and cleared with him. I filed a grievance and still waiting to hear back from Union. This seems like a way of intimidation to keep us from calling in option days. Has anyone had this happen?
