I am a senior leader in my company and there is a small possibility I may be made redundant in the coming months. I have been with the company for just shy of 5 years and am on a 1 month notice period. However, a little while back I was asked to sign a change to my contract changing my notice period to 3 months in line with all senior leads - I didn't do it at the time as I disagreed with it, but now am wondering whether I should sign it. Would it impact a redundancy package I'm offered or is statutory redundancy purely based on the length of service and age, and not your notice period PLUS statutory?
