This didn't happen to me but to a friend of mine.

She transferred from the IT department to a small marketing team which she felt was a better match for her skills and talents.

After a while it became quite unpleasant. The other team member (I did say it was a small team!) did not pull her weight and was hostile. No use complaining to the boss because he was having an affair with the other team member!

Anyway, my friend quietly looked around for another job and was offered a post elsewhere at a much higher salary. She wrote out her resignation letter and took it into work the next day. She delayed handing it in, perhaps not wanting a confrontation. During the morning the boss called her into the office and told her she was being made redundant! She took her remaining holiday time and left with a hefty redundancy payment, straight into her new job!
