If something isn't done to protect school staff and children and schools re-open in the way suggested at the moment, there is a huge increase in the chance of a resurgance in schools. To date - and that's with only partial openings and social distancing, there have been 55 outbreaks in schools since re-opening. Although funnily enough we're not seeing that reported much in the media.
Whatever you feel about children's rights we all have responsibilities to keep children AND staff safe. There is a duty of care from teachers / staff and a duty of care towards teachers / staff. If we don't observe that, then schools will end up locking down again, or staff will be striking / resigning in their droves once increasing case numbers start.
It's not possible to say, 'just get them back and no they shouldn't have to wear masks, it's not fair or practical for the children'. We have to look for solutions or this just isn't viable for anybody.
I hope it becomes mandatory in secondry schools for children to wear masks (and for teaching staff) and possibly in KS2 as well. For younger children faceshields would work. Faceshields would also work for those unable to wear a mask for whatever reason.
They can be removed when outside and pupils are able to socially distance ie break and playtimes. They can be removed when eating. Children will not be in them for 6 straight hours.
Rather than giving the country £10 restaurant vouchers why can't money be spent on disposable face coverings? So if pupils need more than one in a day due to contamination, schools can provide them. Hand gel before putting on and removing, spraying masks with non-alcholoic sanitiser inbetween will all reduce spread from / to masks. No, not perfect - but most definitely better than nothing.
Staff should be able to choose what PPE they wear - masks, shields, a mixture of the two... or if they don't want any, then fine - but I wouldn't a child of mine sitting in a classroom with a teacher (sometimes shouting / voice raising ) at the front of the class spraying droplets on children sitting below!
Basically - doing nothing is not an option. We can't just pretend the vius is not there and this will go away. If parents want children taught inside schools, then adaptations, big ones, need to be made and that involves compromise for everyone.
