If there's 2-3 teachers catching Corona daily in one school (15 a week) as stated on another thread why on earth has your leadership team not shut the school? Another school with 66 cases in pupils in one week, why is the school still open?
Before you say the government won't support it, that's rubbish. My DCs school has recently shut for 2 weeks at least to all but year 11 and 13. And they had much fewer cases than above and none in staff.
You should be lobbying your leadership team as they sound useless.
