Its a high street bar chain, so I'm presuming that they won't want any negative publicity!!

Thanks... There's an area manager above the 2 GM's and yes it is a large company with a HR dept. I'm guessing I should send the formal grievance into the HR dept? Do I send it into the GM's aswell? Thanks, again!

Hi guys, Bit of a long one so i'll apologise first!! I have worked with the same large company for a total of 2 years, the last year I have worked as assistant manager within the company. During these 2 years I have worked on average 45 hours per week, apart from a period of 5 weeks when i was working on average 70 hours per week. I now have two new general managers who have dropped my hours to 12 hours and subsequently the last 2 weeks I have received no hours at all. Upon enquiring as to why this was my manager replied that he thought I had a new job because that was what he was told by another member of staff and as I hadn't turned up to do my 12 hours two weeks before he thought this was true (although i did contact the other assistant manager at this time to say i wouldn't be in due to being ill.) My contract does state that i am contracted to work up to 48 hours per week as and when the business requires me, so I don't have fixed hours on my contract so I am unsure as to whether I can raise a grievance against them for this as i feel that I now have no other option but to look for another job as I am receiving no income. Could someone please advise before I go in all guns blazing! Also, 2 weeks prior to me receiving just 12 hours at work my manager sat me down and said that he was unsure of 'my commitment to my job' as he had recently found out I was at university part time and as I had forgotten to a pass a minor message on to him, would prefer it if he took my responsibilities off me and made me bar supervisor instead, even though none of this had been mentioned to me previously. He said that this 'was not a demotion' which was obviously utter rubbish, however my pay did remain the same. I accepted my demotion as I felt I had no choice and worked for 2 weeks in my 'new' role. In order for me to be bar supervisor, a supervisor card is required and upon the start of my shift 1 week later i found that my supervisor privilages had been removed from my card, so I had obviously passed supervisor and had been demoted to bar staff without being informed! I did not raise this as I have a bit of a temper and the week later I had 12 hours so I presumed I was being forced out (being an assistant manager its not uncommon that I know how it works) so did not know how to go about anything. Demoted to bar staff without reason and hours cut to zero in 3 weeks!! Could someone please advise me on whether I have a case for anything and, if so, how I go about it. Thanks very much.
