I posted earlier in the month saying that I was having problems with my timetable (I am a teacher)as I was told with two days notice I had to work a Monday afternoon when I didn't have childcare. It was eventually all sorted (I had to get the union involved) and the timetable was changed. This affected someone elses timetable and they sent a really nasty e mail to my line manager (who happens to be her best friend) saying how angry she was, how selfish and horrible I was, how my contribution to teaching was doubtful etc and she also copied the e mail to all senior management. I have complained and she has been made to appologise (via e mail) but now I have to return to work and see her and I'm not sure how to handle it. I also have to see my line manager who told me I was cold and unapproachable the last time I saw her. Any advice ?
