To the OP, actually in teaching things are going the same way as in the NHS, you are covering multiple patients due to staff leaving, I find myself now on cover every free period due to teacher shortages, and I have had to run two classes at once (which was a nightmare)
But that is doable, its hard graft, but I'm paid to be there, however the knock on is that the admin, much of it pointless and unproductive goes over to the evenings and weekends.
I have recently had dealings with the admin side of the NHS, and it is an out of control inverse pyramid if ever there was one.
Striking is not the answer for me or you, what our respective unions should be saying is "look, this is your job, these are the things you are supposed to do, the rest of it we are collectively not doing"
A mate of mine who is a GP tells me a huge tranche of his time is taken up, like mine, with pointless admin - so he simply can't focus on his key role and gets worn out.
Rather than collectively standing outside with a plaquard saying we don't like it, we need to be inside, doing our core job collectively "work to rule" as it were and effect change from the ground up.
I just can't get behind something that will actually harm people and cause more misery.
