I have had some pretty shitty Team Leaders/Managers.
I can think of two immediatley.
One Team Leader was so miserable she never even spoke to us before about 11am. She was always away from her desk, on fag breaks, down at the kitchen eating bacon butties or just generally sciving. I remember coming back from holiday one morning she never even said welcome back, or asked how my break was nor did the fat cow even say good morning!....She also reeked of fags, coffee and cheese and onion crisps!
Another one of my Managers put me on extended probation (not just me but all four of us new guys) for no reason what so ever. He just said he wants to see more from me, exactley what he meant who knows!.
What about your worst Boss?
