I am planning on leaving my job at the end of summer as i have mentally checked out. My Boss pressured me into applying for an open position and is now pressuring me to do overtime. My days are already 4:30am -5pm. I am a union employee so OT cannot be forced. I have respectfully turned it down as being trained is pointless because i plan on resigning july/aug. He is noticeably upset with me and told me he will not stop asking. The promotion will automatically kick me out of the union and my boss can then force daily overtime on me until i resign. Interview is on Monday. How do i get out of this/turn it down. Didnt want to leave on a bad note but not at the expense of my sanity.
