I've recently reduced my hours at work from 36 to 32 hours a week, I had to do this as I went into a new role and these were the new hours. The only good thing about reducing my hours was that I went from a 5 day week to a 4 day week. This meant that I wa able to find another job on my day off.
Now I've been told I need to work 32 hours over 5 days. I feel so annoyed as if I had known this I would not have taken on this new role.
What does your new contract say about your hours - when they are worked and what degree of flexibility there is for either you or the employer? If you've signed a new contract specifically saying 32 hours over 4 days, it's obviously more difficult for them to change than if it just says 32 hours, and either doesn't specify days or provides flexibility to the employer.
