I'm working my notice have had some trouble with HR over holiday days. They won't pay in lieu and won't let me take them at the end in one block. They want me to basically work three /four day weeks over six weeks to use them up incrementally. I'm being made to feel unreasonable for saying I don't want to do that, as I can't then use them for a true break. My manager, to shut me down, has sent an email copying HR accusing me of turning against my employer. I feel bullied, and don't think I'm being unreasonable. Should I let it go or raise a grievance? I'm not expecting much of I do complain and know it will make things tougher in reality. But I am getting too old to put up with things like this without speaking up. Or am I overreacting?
