NC'd for this as details make me quite identifiable.
I'm a teacher. 18 months ago my school's staffing system was restructured. I was a middle manager on a responsibility allowance. My job title was changed (effectively to a demotion) and my salary reduced, with three year's protected pay given. I went on mat leave in May. Whilst on leave, I saw a job advertised at my previous level of responsibility, with my previous salary. I applied for it and got it, and start in February. I won't therefore be returning to my previous school following my mat leave. My mat leave contract says that if I don't return for 13 weeks, the local authority is entitled to reclaim my 12 weeks of 50% pay. However, I wonder if I have a possible argument that I was on protected pay for a finite length of time - clearly, the reason protected pay exists is to give you time to find a new job on the same salary as you had before, or to make adjustments to your circumstances so that you can afford to live on the reduced new salary. Could I argue that given that I had protected pay for three years, it would have been foolish to pass up on this opportunity just because I was on mat leave? If I hadn't applied and had returned to my old job, there are no guarantees another would have come up on a similar salary. I should perhaps add that if it weren't for the reduced salary I wouldn't have been looking for a new job - I was very happy in my previous one.
Any thoughts from anyone would be much appreciated.
