I got hired under the premise that I would have 3 days of holidays( also called Paid Time Off, or Leaves in some countries) a few days after I joined.
Now, I am being told that this year I get 3 fewer holidays because of that. I remember having the previous agreement in writing from HR, but I cannot find it yet. Now HR is arguing that there has been a misunderstanding and that since I got 3 more days then, I am going to get 3 fewer days this year, than what I would normally be entitled to.
I feel that allowing this would set a precedent for them to further try to restrict my benefits.
How should I proceed? I feel like it was a verbal pact with HR since I specifically asked for this point several times, since they wanted me to join ASAP while I could have joined after a vacation that I was enjoying then. (I have in writing them telling me to join as soon as I could due to the request of one of the managers). I feel vacation is a perk the same way that salary is.
