I'm an assistant manager for a retail store. I gave my resignation with 2 weeks' notice. My boss asked if the 2 weeks was negotiable, and I agreed that I could probably stay longer to help with the transition.
We are allowed 1 full weekend off a month and mine was scheduled towards the end of my notice. When the schedule was posted, I was on a 9 hour shift for that Saturday. I had made plans with my children for that weekend.
Any advice on how to handle this situation? I want to leave on good terms, but feel like this is a petty move on my bosses part and I definitely am less inclined to help past my 2 weeks.
