right update....i spoke to my manager last week and told him politely that as it was detrimental to my health i was saying that i would not do the extra work..his reply was to say that he would contact HR after Easter.so this Monday and Tuesday i refused to do the extra work and i coped well with my normal job...

he came to me as i was leaving on Tuesday and told me HR was coming to see me for a meeting on....wait for it

an hour before lunch has to be ready on Tuesday....what the  f####????? how am i supposed to get lunch all finished while i am in a meeting with her.apparently its the only time she has available

i think they have all lost the plot.

will update on Tuesday evening
