Sorry - this is quite long...
I used to be second in English dept at my current school. I took over as acting head of dept when the HoD became ill long-term. Whilst doing this I fell pg with dd. Whilst I was on mat leave the old HoD resigned and the job was advertised. I decided not to go for it as I wanted to work p/t. I negotiated my terms with the Head whom I get on well with and who told me he didn't want to lose me. So I went back with a good timetable and some responsibility which I was paid for but only had to work 3 days a week. The school appointed a new HoD, a real "whizz-kid" bloke who, IMO, is using this job as a stepping stone to greater things, i.e. Headship or even educational advisor for Ofsted or sg like that.
I was already back at school when he started last Sept. In May they were sorting out the timetable for this coming school year and unlike in the past, my HoD didn't discuss it with members of the dept; he just allocated classes to teachers. I was Ok with my timetable though and I had 3 exam classes as well as other year groups, that is a Year 9 SATs class, and Year 10 and 11 GCSE classes.
A few weeks later I thought I was pg - hadn't done a test but had all the "right" symptoms, so I was going to test at half term. Before we broke up, though, I told my HoD that there was a possibility of me being pg. I only did this because the end of term was the cut-off point for making any changes to the timetable. I told him that I wanted to make sure my Year 10 class wouldn't be disrupted if I left mid-way through their course. I suggested that he and the Head try to think in advance of a good speciality teacher to fill in for me, e.g. one of the deputies who specialises in my subject. I stressed that I might not be pg anyway.... which I wasn't.
So I came back after half-term and told him this. Nothing more was said until 2 weeks before we broke up for summer. I got my timetable for this year and saw that I no longer have my exam classes; my Y11 group has been split up so that they all have a different teacher and my other classes are team-teaching and support classes. In other words, I've been treated like a supply teacher rather than someone with 10 years experience. I told him I was not at all happy but all he said was "well, I thought you were pg, so I was just trying to lessen the disruption of you leaving". The Head has been sympathetic but can't do much because all the timetables are now in place, altho he's promised me it'll never happen again.
I'm still really angry and not looking forward to Sept, which is not like me because I've always loved my job up to now. Is it worth still showing my displeasure when we got back or just put-up and shut-up?
