First let me say I absolutely support schools and school staff being asked to do whatever is necessary.
I'm not sure why opening over Easter is necessary though. Staff are already on their knees from all the upheaval over the last couple of weeks and the next two will I'm sure be testing too. Society is already geared up for us to be closed for those two weeks. I would expect staff to go above and beyond in the coming weeks but I'm not sure what's to be gained by removing this valuable break, apart from perhaps losing a lot of goodwill.
What am I missing?
