I'm feeling pretty upset at the way my school is treating me at the moment. I went on maternity leave last year, and returned to school in March this year. Prior to my leave, I was a 0.6 Year 6 class teacher working Mon, Tues & Wed (I had previously been full time but decided when pregnant to reduce my hours, and someone else was employed 0.4 to be my job share). The school's PPA teacher was then appointed as my maternity cover. When I returned to work in March, I agreed with the HT that I would happily do the PPA role from March until July on the clear understanding that I would be returning to my class teaching role in Sept. The HT agreed this with me verbally (I only have a sketchy outline in writing). I thought this would be the least disruptive course of action for the children this year, and I reassured I would return to my original role in Sept. However, the PPA teacher who has been doing my cover has since said she doesn't want to return to PPA. The HT is now considering her options, and is renegading on her word and promise to me that I would return to my classteaching post. I feel terribly upset, and feel I'm being discrimiated against because I went on maternity leave. Had I returned to the classroom in March, then none of this would have been up for discussion. I've contacted my union who are very supportive, and say I should wait to hear the HT final decision, but it is becoming increasingly apparent she is unable to keep everyone happy, so is refusing to make any decision. Help.
