I didn't mention blanket closure @MarshaBradyo
Interruptions - schools open, schools closed, classes open, classes closed, some siblings in, some out, last minute changes, early collection etc etc - just so disruptive to everyone, including children's learning and parents working life. ( and no furlough to support parents).
I pointed out that under legal requirements of KCSiE, schools cannot stay open without their safeguarding leads in attendance. This is be two staff members in small schools. Cobbling together large groups of children, just because it is convenient for parents won't meet risk assessment ( including things like fire, teacher child ratios etc)
We do sometimes manage make 'local arrangements' with other schools to try and keep schools open, but it wasn't always possible in my LA as 'other schools' similarly had no safeguarding staff available - whole schools did close in December.
Legislation could have been changed, but of course the government don't want to be accountable and responsible for incidents in schools which they have decided that safeguarding children is no longer a legal requirement.
