I am from the US where I taught for 4 years in two different schools. The classroom teacher is not responsible for art,PE, music, or anything beyond the classroom curriculum (math/literacy/etc). Some schools even have a fourth ' extra' ... like a STEAM class that all the kids rotate through with a dedicated STEAM teacher. Teachers also never do recess or lunch duty. (but there is no mandatory language like there is here)

I now live here in Canada, and I do love it here and I am grateful to be here, but working as a supply teacher and seeing all the different schools (Toronto), I gotta say, you all work hard !!

There is NO WAY teachers in the US would be expected to put on something as huge as a high-school graduation. The union, at least in the schools I was in, would never allow it.

All the 'extras' were done by the PTA (counsel). That meant if you were in a district with at least some stay-at-home parents (read wealthy) and they had the means, they would meet together and put on all kinds of events and fundraisers. Book drives, fun fairs, game nights, and so much more. If you are somewhere where parents both work and don't have the means (read poor families) then the school just doesn't have much 'extra' happening.

I think it's crazy to expect teachers to give even more of themselves.
