I used to completely pander to my manager by working through my breaks, staying late, completing tasks that are above my pay grade for less pay etc
I recently started to (politely) insist on taking my breaks and leaving on time and she now thinks I’m not a “team player” any more. Her demeanour has completely changed towards me. She’s frosty both in person and online, think borderline rude comments verbally and condescending emails. She even told a senior manager this week that I had worked there for significantly less time than I had (I started in 2019 but she told the senior manager that I started this year?) which I felt was a passive aggressive dig to make me feel irrelevant.
I don’t see how she would completely forget about my existence for the previous 2 years as we were actually quite close before I started to stick up for myself - we went out for drinks etc.
What would you recommend to do in this situation?
