We’ve had no contact from our school until 2 weeks ago.
If my DDs teachers had been teaching other kids whilst we’ve been struggling at home (both working and crappy pdf sheets to do) then yes I’d be beyond miffed.
If it’s being carried out by a contracted teacher in their working hours, then personally I think it’s all shades of wrong.
As a side note a friend who works in the state school system has said that teachers have been actively encouraged by the unions not to teach and dissuade at all costs in order to negotiate a better pay deal.
The last paragraph is not my opinion, just what I’ve been told.
