I have a new boss who joined less than 2 months ago. A few weeks after she joined I resigned (not her fault I had been looking and had just been offered a role I wanted). Now I appreciate my leaving right now is not ideal due to staffing issues and boss being new. I've been nothing but nice and helpful wanting this transition period to be as painless for everyone as possible. However this new boss is quite a bitch!! She has done nothing but make my life difficult since I handed in my notice last week. I've so far been trying to be the bigger person throughout but can't help feeling like the next 3 months are going to be hell!! I now want to be petty and fight back with lots of little annoying things. Am I being unreasonable to ask you for ideas on how I can piss my boss off back?
