Yes, I am, and have throughout. It's in no way my job or anywhere near it, and the £££ per hour value is silly, if you want to look at it that way, but it is the most effective, safest, fewest people in the mix solution.
What's the alternative?
Primary kids can't clean a toilet themselves, and they can't go whole days without a toilet, but we've decided that we can't leave the toilets uncleaned for the whole day at a time.
This being the case, toilets need cleaned, so its teacher or cleaner.
If teachers are right re kids and social distancing not being possible (and I firmly believe that they are right!) then the teacher is already completely exposed to that bubble of kids - they're not put at any increased risk cleaning the loo.
In contrast, the cleaner coming in is put at greater risk - they're exposed to each bubble unnecessarily. That's bad for them, and bad for all of us as we're creating more potential transmission chains.
Frankly, too, a shared cleaner moving room to room during the teaching day seems like a very good way for all the 'bubbles' to end up cross-exposed, but schools (and the Government at this point) simply don't have the budget for a dedicated cleaner for each class.
We're left with the reality that the teachers stepping in simply seems like the safest, most effective way of dealing with this issue.
Now, I appreciate that this was not part of the job description when they took the job - as I said, neither was or is it in mine or many other people's - but things change in the middle of a crisis and we all just need to get on with it now as best we can.
