Redundancy - is this fair?

lyndsey80

I have been working for a company for the last 6 years on a casual basis. Over the last year I was working on a part-time contract only doing 4 hours in the evening.
They needed to reduce the contracted hours by a certain amount and invited people to voluntarily take redundancy.
I went to my consultation and was told my casual hours were not affected, it was only my contracted hours. I was asked what shifts I could do, I gave them my rationale. I was told my contracted hours would NOT INCREASE. After sleeping on it I decided I didn't want to go through all the consultations, interview for four hours.
They are now almost at the point where they have enough people being made redundant... My question is, if too many people take redundancy or people leave as the shifts proposed to them are not suitable and the people that remain get contracted hours - do I have any right for a claim if people get more than the contracted hours they were on before? As I would have stayed and stuck it out had I had the opportunity to have more contracted hours.
Hope that makes sense.
Have now received my redundancy cheque but no P45 (presumably as I still work there on a casual contract?)
