Because some schools do seem to be managing this much better than others.
Of course there are variations in how schools are managing, depending on community rates, their pupil and staff profiles, the physicality of their buildings, how large the school is, the way their pupils travel into school, the number of CEV families including staff.
And sheer luck.
In the same way that some hospitals, or care homes, or residential seem to be managing better than others.
But I don't remember seeing threads about how it was the responsibility of frontline health care and care staff to lobby the government for suitable PPE, cleaning etc. Posters seemed much clearer where the responsibility for central government policy lay.
The secondary school situation has strong similarities to that in care homes earlier this year. Central government policy was to vacate as many hospital beds as possible which in practice involves sending patients untested for covid into care homes, where the virus ripped through.
With schools, central government policy was that they'll be open, full time for all children. Not surprisingly, having hundreds of children mixing in an environment where it isn't possible to properly socially distance, with minimal other mitigation measures, and certainly not routine testing even if known to have been in 'close contact' with a positive case, has led to the virus tearing through schools.
If you think this is because teachers haven't done enough lobbying, then I honestly despair.
