I'm a teacher, I started my present job in April 2006. It was a post created for me after I applied unsuccessfully for a senior role. My boss has always been really positive about my work and has also supported me in gaining a significant professional qualification. I got pregnant the first time after I'd been in post for a year, and returned to work last July, working 4 days a week. When I got back, I found that a lot of the work I'd done had been dismantled, and also that the staff I'd been allocated meant that I had to substantially alter the way in which my team worked. Also my own timetable had substantially changed so that the majority of my work was now in a different department.
I didn't want to make a fuss about any of this at the time but just got on with doing the best I could with the resources allocated. Last October my boss asked if I would be willing to take on leadership of a new team in addition to my existing role. I agreed, although I was anxious about my capacity to manage all of this in four days. In January, I realised that this was not working and stepped down from the extra role. At the same meeting I told my boss that I was pregnant again.
Since then his attitude has completely changed. He has called me in about my absence record, and again to criticise me for the way I am managing my team and workload. In a staff briefing he was openly dismissive of me, in a way which has caused a significant number of my colleagues to comment on how unreasonable he is being. I feel that he is punishing me for resigning from the other role, but also for being pregnant. I have written to him in response to his most recent criticisms, one of which was based on wholly false information. I don't want to get my union involved as I prefer to deal with things myself, but feel I am running out of options. Should I just keep my head down, or is there any other course of action open to me?
Sorry this is so long...
