Harassment is real and leaving not always an option
My wife is now waiting for the outcome of a bullying suit she lodged last year within the Australian Public Service.
She is "fortunate" in that she has umpteen witnesses, written chains of evidence (including slanderous comments scrawled across files) and a personal work history of excellence including her work being used as a national example of good reporting. The bullying was sustained over a period of months.
Her claim, against her boss, is about outright bullying, nothing related to sexual orientation or religious practices.
She does have the disadvantage of not only being a union member but being the local union representative and as such being very much on the wrong side of the politics in Australia at present with the "Work Choices" legislation.
With regards to "just leave" - sorry but
1) it is not always that easy to get another job, especially once you are over 40
2) within the Australian PS at least, once EITHER of the parties in a case leaves, the case is dropped. No penalties, no black marks on a record, no closure and the bully is free to go ahead and carry out their behaviour with other victims. (My wife was not the only victim in this case.)
