I'm not in Scotland but I do appreciate the concerns that pupil-facing staff are currently experiencing. Are you actually prevented from wearing PPE at a level that you feel safe with?
If you are, that is not something that you should have to deal with and I suggest you immediately discover at what level the decision that prohibits the amount of PPE that you can wear and you challenge that decision.
Even if PPE wasn't available to many highly vulnerable front-line key workers at the start (thinking of all those NMW/Zero Contract Care Workers, Cleaners, etc in the first instance) I'm sure it's available now to All Workers that want it.
If the School won't pay for it, I'm sure once the School Guvnors know about it, you'll be re-imbursed and apologized to. At least this would be the case in all the Schools i've Guvved on.
In England, individual Schools are emailing Parents with their first Outlines of Opening Provision.
It really needs to be down to each individual School, whilst I am aware that various tiers of guidance from different centralized sources are being given; the greatest untapped resource is each school's local community.
All those Parent Volunteers that usually turn up to Read with pupils, the PTA, your Parish/Ward Community Groups, etc - many of these will redeploy and carry out cleaning, SD organization etc.
To make sure that their Community's Children can get back to some sort of School.
Also, given the additional Central Govt Funding that was available to Schools up to the end of Summer 2020, including additional Hygeine and Cleaning Measures, it would seem preferable that all immediately affected ensured that this Aditional CV-19 Hygeine Funding was available for English School opening in Sept.
If your School/MAT didn't/doesn't apply for the available CV19 Hygeine Funding or pressure to make it available for Sept New Term, then that is not a failure of Govt, Parents, Society - nor the Student/Pupil Victims - is it?
