From 2003, until 2008, I had the worst possible Manager imaginable. He was a bully, and was controlling in the extreme. Over those 5 years, he steadily reduced my self esteem to almost zero. I left in October 2008, by which time I was on the edge of a mental breakdown.
Only after I left, was he found out and sacked. I blame myself, for allowing his truly awful behaviour to flourish. I vowed I would never let that happen again.
My advice to anybody in the same position, would be to tell and a similar Manager to **** ***, very loudly and very publicly, and leave.
