Everyone else usually takes Monday's and Friday's off, and he doesn't say anything. My manager gave my night supervisor the power to approve or disapprove my time off. I asked for Monday off, and my supervisor always waits until the Friday night prior where I have to to remind him again. This time I sent out an e-mail reminding him, including my manager and my project leads. My manager replied saying he was okay with it. I replied back thanking him. But then my supervisor got mad, and replied back, "Sorry, not Monday. I may need your help." I made it a point in the past not to ask for Friday's off because it's the busiest day of the week, so I was afraid since my night supervisor rejected my Monday request, he certainly reject a Friday request. So I CC'ed my manager's boss who is really in charge of all of our group, saying I accumulated my maximum number of time off hours and I had to take a day off next week and I'd rather take Monday or Friday off rather than a random day in the middle of the week. I asked for Friday of the same week off. Well I don't think the supervisor realized I included the big cheese (big boss man) in the message and he replied back saying he understands but he'd prefer I take a random day in the middle of the week off because Monday's and Friday's are busy. I called my manager and left a voicemail for him, and replied back to the e-mail saying to my manager, "I'm not sure what to do." A few minutes later the night supervisor replied back with, "I'm okay with you taking Friday off." I think it's because I cc'd the big man. To be honest I don't think my night supervisor and manager like me.
