Our department has over 150 employees divided over 5 shifts. One supervisor- Frank, his first go-to answer was always “Can't support it.” The other 4 shift Supervisors would bend over backward to give you time off & apologize if they could not.
For example, A new person was feeling down at work. I asked what the problem was. He mentioned his son was graduating and he can't get the day off. I asked if he gave a reason to our supervisor. He stated “no.” I went to the supervisor & asked if he knew the new guy's son was graduating and that is why he needed the day off. Our supervisor was shocked & stated he should have told me this. He called the new guy & gave him the day off. We were short-staffed then & the supervisor came in & worked for him.
Franks's employee in September requested a day off in February for his daughter's wedding. Without even looking at the schedule Frank stated “Can't Support it.” The employee had to go over his head & threaten to quit before he got his day off. I told him it's easier to call in sick & get paid for it, than waste a vacation day.
