I'm a shielding teacher, with the benefit of 'the letter'.
My husband is also a teacher and I've been looking into all the legal implications of what might may ahead. I found this site particularly helpful and addresses most of the scenarios possible, all quotes are taken from here:

OP this bit might be particularly relevant to your situation (and my husband's). Don't quit your job because your employer fails to maintain a safe workplace:
'If an employer decides to require the employee to attend work, and they refuse, this could be a disciplinary matter.However, much will depend on the circumstances – for example, the employee may want to self-isolate because they genuinely and reasonably believe themselves to be in imminent and serious danger perhaps due to the employer’s poor management of an existing infection or contamination, or because colleagues are not following recommended hygiene or social distancing guidelines.Disciplining an employee or withholding pay in those circumstances might be unlawful detriment or, ultimately, unfair dismissal.'
And for those of us shielding, consider this too:
'Individuals with underlying health conditions may well qualify as disabled and therefore the employer would be under a duty to make reasonable adjustments. Again, this might involve identifying another role that can be done from home or temporarily suspending them on full pay if this is not feasible.'
As teachers, I know we can feel protected by the unions, but I think having an understanding of employment law is really important. I'm always surprised how ignorant SLT can be when it comes to their legal responsibilities.
Thank you for this thread!
