Irish that's terrible! I hope your Dr can help back up your argument. I take it the school didn't even think about this in their risk assessment despite you raising it several times (if they did a risk assessment that is. We all know employers are supposed to but I'm learning that when it comes to pregnancy, antenatal care and maternity leave etc what employers are supposed to do and what they actually do are often rather different!)
I'm getting fed up with work again. I saw my midwife on Monday to have bloods taken prior to having my anti-d injection. She said she'd just found out our local hospital have changed how they deal with anti-d, and that rather than having the injection within a few weeks of having bloods taken they will now only do the injection within one week. They have one anti-d clinic a week on a Friday afternoon. I told the midwife that was fine, and I should be able to make an appointment this week. So she took my bloods then rang the hospital to arrange my appointment.
I got back to the office to find one of my colleagues has booked the same afternoon off as leave. Only one person from our department of three is supposed to be off at any one time. I told my boss I have this hospital appointment which is time sensitive and will mean I'll be out of the office for a fair chunk of time as the hospital is almost a 2 hour round trip away. I also offered to make up the time (even though legally I don't have to). He said that was fine and not to worry about it (muttering under his breath about how he was going to have to put up with this until April 
). Then I notice in his diary this morning that since finding out about my appointment he's arranged meetings out of the office all afternoon tomorrow, which means there will be nobody covering one of the departments my boss and I work across, and only one person covering the phones for the other department we deal with (and she seems to have an aversion to answering the phone anyway).
When the director with overall responsibility for our departments finds out he's going to have a shit fit. And you can guarantee the person who bears the brunt of his anger won't be the male Chartered Surveyor who booked himself out of the office knowing there wouldn't be anybody else in, or the male graduate surveyor who booked leave just because he wants an afternoon off. Oh no. It will be the pregnant woman with an important medical appointment to go to which she can't change at such short notice 
.
I'm getting really fed up with all my boss's little comments and asides about my time off. I've not even taken that much, I used my holiday allowance for my routine scans and GTT as it's just not worth the hassle from work.
