I work in a huge high school, and have been in school from Lockdown. Initially, on a key worker kids rota, and from mid June teaching a year 10 bubble.
I think this will actually work well, and is manageable. There are too many people ready to pick holes in the plans (often before they've even seen them) and criticise. These people often have unrealistic expectations, they want guarantees. Sorry, but there are no guarantees about anything regarding this virus. So we have to accept that and get on with it.
We need to understand that there will always be flaws. There will always be risk.
We will have local lock downs, and positive cases will mean that some schools will have lots of students off at one time. But that is surely better than what we have now isn't it?
There is no magic wand to protect everyone and ensure staff and kids are 100% safe. There never was before Covid, and there won't be afterwards.
It won't be an easy Autumn/Winter. But the fear and negativity isn't something we should pass on to our kids. I'm not saying we should be reckless, we should do all we can to minimise risk. But school life has to return to as close to normal as it can in the Autumn, and whilst it will be a challenge, it needs to happen for the wider well being of all of us.
