I've worked my vacation week twice. once I had planned a trip that fell through so I didn't really have anything to do and I ended up taking a week off later, basically informally rescheduling my vacation. I don't live "paycheck to paycheck" so people's logic about that later week making a hole in my pay doesn't hold any water for me. The other time I kinda needed the extra money (again not that I live paycheck to paycheck). and I only wanted my birthday off which was friday, and I just showed up on monday, I guess they just didn't realize I had a scheduled vacation because it wasn't an issue until thursday when I told them I wouldn't be in tomorrow which they balked at. I had also warned them wednesday but I think they weren't paying attention. Friday they called me a whole bunch of times I answered once and calmly told them about my superstition about birthdays being unlucky and that I wasn't coming in. they told me that I would be in big trouble. it only reinforced my superstition. monday they fussed at me, had a 5 day ready to go, but i had already filled out a harrassment grievance in advance and had documentation of my vacation schedule, which i always get after them trying to reneg on a vacation involving a family trip to ireland years before. in lieu of suspending me, my manager flew off the handle accusing me of shouting and cursing. so i wrote out a harrassment grievance on that.
i don't really get what's so bad about someone working their vacation if they do it of their own volition. I'm fine with the language either way, i just don't see what the big deal is.
