I was the subject of harassment by a co-worker for over 2 months. I repeatedly asked my boss to deal with it. He had a sit-down with myself and the other person after close to a month in to the problem. The behaviour continued. I elevated my complaint to HR almost a month later. The problem was solved with the other person. The very next day, my boss assigned me to a less desirable shift. I was left stunned. I went home part way through the shift (both from exasperation and exhaustion). The company then presented me with a warning letter about leaving and that I never reported my departure to anyone. I had indeed informed my co-worker. I have been terminated (for cause). There are other elements but this is the gist.
