What is reasonable in terms of cover?

[SansaSnark]

So, I'm NQT + 1 and this is my first year of being asked to do cover at school.

I have an absolutely rubbish timetable this year, which means all my PPA is on a week 1, and I have none on a week 2. On my last week 1, I lost my "free" on the Friday to cover, and now we are back to week 1, I have lost my Monday "free" to cover. I am dead on the 90% teaching time, so it's not like I have extra PPA/free periods, either.

I have a full teaching day tomorrow, so I will have gone a week and a half without any PPA time. For context, this time included a parents evening and time to get reports done.

Would it be unreasonable to raise this with my line manager and possibly my union?

I know school are in a really tricky situation as we have a lot of teachers off and it is very hard to get in supply at the moment, but I feel exhausted and like I am really struggling, and the thought of losing more PPA time this week is really stressing me out.

Yes and yes. You cannot be asked to cover in PPA.

Do you mean you have 2 weeks worth of PPA in one go, every 2 weeks? Then you have other 'frees' in which you've been asked to cover?

I read it as the PPAs have been taken away as cover. Yes, I think I'd raise this as an issue. Okay if it is an absolute unforeseeable emergency but for this to happen to you twice in 1.5 weeks is totally unacceptable. Union would be all over it, I should think.

You cannot be asked to cover in your PPA. If you have additional frees, then it could be seen as ok (although even then it's meant to be rarely and never for a foreseen event). I would approach your union.
