The thing is, it would be very, very, easy for me as a teacher to swing the lead if I so wished.
I'm a good teacher & a terrible presentee-ist who's gone in with broken ribs (sustained very audibly in a teacher sporting event - ouch) & every minor illness going.
If, say, I rang in next week saying I had crippling back pain & my doctor had signed me off for three weeks, it would absolutely be accepted. By then there'll probably be a covid related closure if there's going to be one, & I'd be very vocally happy to supervise distance learning, monitor students who couldn't attend, do everyone else's marking etc etc.
Return early October briefly, put back out again. That takes me until half term.
Covid symptoms in early November, oh dear, need to self isolate. Covid symptoms turn out to be flu, oops, couple more weeks off. More school closures happen & miraculously I'm invariably fit & raring to go every time school closes anyway.
After Xmas, stress & anxiety caused by being out of the classroom for nearly a year...oh dear, I still can't come in.
By the time anyone put me on capability, it could be Easter, & hopefully by then we are over the worst & I stage a miraculous recovery. Or, I hand my notice in, go off sick again & spin it out until the end of the summer term.
Now, I would not do any of this as I'm not naturally dishonest, & anyway I'm rather looking forward to going back, albeit with some trepidation.
But teachers are scared. & the whole 'get back in the classroom or you should be fired!' shtick is likely to lead to variations on the above.
We all know that teachers are getting younger, & retention of experienced teachers is appalling. More bashing will just lead to more 'Ah bollocks to it, I'm done'.
Government initiatives to get more bright young things into the classroom demonstrably don't work - people suck up the bursaries or whatever & then bugger off.
I'll be in front of my classes in September come hell or high water, as I've done for 20 years. Because I like my job. & I'm willing to take the unusual risks this year. But a bit less of the berating, please, because there are plenty of perfectly competent teachers who don't especially love what they do, & would ditch it without a backwards glance, & they are not easily replaced.
