@TheKeatingFive. This past summer holiday I did holiday cover for two weeks for summer school and a week in our uniform shop. We get a five week holiday in our school.
I then spent the last two days of the holiday covering lateral flow testing for the whole school to return. And covered for exam results collection as someone went down with Covid last minute. And I'm not even a teacher so didn't have planning etc to do.
I spent less than two weeks with my DS this summer. Which is fine, many have to do exactly the same. But that was unplanned for. For those who had younger kids they had to arrange childcare which they normally wouldn't have had to do. Many teachers (including the head teacher) were also helping out so we could spread the uniform collection around for Covid safety or give the new year 7's a chance to learn their way around the school.
On top of that they were preparing rooms for the new term, dealing with questions from parents and sorting out final plans for opening with new Covid rules. Some teachers were helping our 'soon to be examined' students with extra work on line as well.
During the Easter holidays some teachers ran a 'little school' again to support vulnerable kids then went straight back to normal teaching plus doing on line teaching for those kids who are self isolating. That's not changed for two years. Just because a child is isolating doesn't mean lessons stop in our school. Every teacher sends work home on line and some have the child join a lesson on line if they are well enough.
So teachers (and admin staff, like me) are stepping up. We're not lounging around in our gardens all summer.
