The answer in my case is Yes - discrimination of the N th degree, leading to a nervous breakdown, they followed that up by more of the same plus blackmail, bullying, then to get out of it they made me an offer they thought I couldn't refuse, but said I had to consult a solicitor so I did, my solicitor had the temerity to ask questions, they refused to answer saying they couldn't be bothered if I was going to be awkward and would just discipline me and sack me with no payout - so I wimped out and took the money and sat and cried a lot for a long time.
And that's just the short version.
If an employer wishes to sack someone - there are certainly ways of doing it legally without resorting to such behaviour. If they don't know how - then they probably aren't fit to be employing people in the first place quite frankly.
Sheena - fair enough, good luck to ya Gel - but please don't make yourself ill because of it. I'd have been far better of telling them to stuff their job when they started the discrimination in the first place instead of trying to follow the laid down grievance procedure. They didn't follow their own rules - why the hell did I ?
