I was so excited to switch over to another department after being overworked, underpaid, and unappreciated. My new position had the same benefits, but with better pay, great hours, and there was also a balance in the workload. I gave my two weeks notice to my supervisor and did all the prep work for my fellow coworkers. On my last day, I got a call from my future supervisor, that the offer has been retracted due to my current supervisor explaining I am not qualified for the position, but would gladly take me back to remain working in my current position. I found out my supervisor is known to sabotage people leaving the department. So I took it to HR, with documents and anything I could use as proof against her accusations. Though I did not get the job offer back, I did get another interview and was able to move to another position.
