My project deadline is coming up and I need to deliver some things asap (which got delayed mostly because of inexperience with the task at hand and limited communication with some colleagues). The "problem" is that I also have to take a certain amount of vacation days until the end of the year, two of which are tomorrow and the day after that.
I am feeling bad for taking this vacation. I did not travel anyway, so I would much rather be at work for the next two days. My crazy thought was to call and cancel these vacation days and try to negotiate taking them early next year or not at all. My target is not to ask for any monetary compensation, in case these days cannot be transferred to the next year.
It would be no problem for me to work a couple more days. However, I am not sure how professional this would look. Also, I work in Germany and I am sure there must be a law against such things, to protect employees (e.g. I have to take a certain number of vacation each year). My boss certainly did not ask or encourage something like that and I am positive that he would never try to exploit me by asking for something similar in the future.
My current plan was to try to reach him tomorrow by phone and ask about it. Would this make me look bad?
