Yep. And our 'rolling year' is an academic year, i.e September to September. There's no way anyone is rolling into sickness trouble 2 weeks into September. 10 days or 3 periods of absence is the rule.
But it is all about keeping schools open. With the situation I've explained today, and even though my management are bending over backwards this evening for me, the briefing manager said when explaining the situation that there will be no self-isolation for the whole school that has been in close contact with her or the kids she's had contact with until/if she comes back with a positive result. My situation is being treated differently because a) I have underlying conditions and b) because they are scared of me because I'm not afraid to speak my mind.
I won't be going back for a few days. Everyone else will. And, as
Pingety Pong says, this does not make logical sense, only economic and political sense with the decision schools must stay open at all costs.
