More teacher bashing!
1) Teachers do not decide to shut schools and are not consulted over the decision. It is the decision of the Head teacher (the boss who is not a teacher any more) who consults with local authority for advice on roads, weather, buses etc, consults the site team / caretakers - can you make the site safe? Do you have enough grit, shovels and manpower to do the job in the time available? And then makes a decision for which he/she will get stick either way.
2) As a teacher I am available for work. If they want me in I will get my wellies on and walk. I have done it before and for what? To sit in an empty, cold building, which, remember the site team declared unsafe. Instead I can work at home and FYI I will mark a set of books, plan lessons for GCSE and A level classes, deal with many emails etc etc.
The teachers might get their weekend back as a consequence of working at home today. I know I will.
