TOM100, my understanding is that if full time, you are 1 x MPE, and if say 50% part time, you are 0.5 x MPE (hence why I said I am now a fraction of an MPE). I think that is what you are saying too? Or am I still misunderstanding? Either way, going part time as you start earning above market rate works nicely in their favour with such a salary structure, enabling them to have their cake and eat it so to speak. The incremental pay structure has more benefits than disadvantages for the company which is why they continue to support it. (They love to focus on the disadvantages because it helps to keep their inflationary pay negotiations suppressed).
