Hello, I am returning to work after maternity leave in September 2012. I hope to be given a reduced timetable of 0.5 (approx). When I left for maternity leave, I was on M4 (in July 2011), my scale rose to M5 whilst I was on maternity leave. Should it go up to M6 when I return in September? Should I have completed anything for threshold? Also, if I am on 0.5, does that mean I will rise up the scale, but twice as slowly? Thank you very much for any advice!
