I agree. There will, be enough foolish staff in school, that want to please and will just do as they're told- whatever the detriment to themselves or the kids - that it will happen and become an extra part of all of our days
I think that is unfair.
I am on a yearly contract. It expires every year and is replaced by another - if the Governors decide to do so, based partly upon the reccommendation of the Head, who is going to take into consideration such little things as whether my punctuality is good, my sickness absence is acceptable, whether my work is accurate, the relationships I have with colleagues, children and parents, or whether I work to rule, refuse point blank to do things that are outside my job description (which conveniently includes 'Any other duties' and generally aren't as 'helpful' as somebody else desperate for a job might be.
I like to think that my current head wouldn't do any such thing to me, but I am acutely aware that I'm over a barrel if they decide I have to do 'Any other duties'. Because previous heads have done exactly that and moved on to more vulnerable staff who didn't have a permanent contract with them when I did refuse.
I think I may escape because I'm already doing something else that is bound by legal timescales and is absolutely critical. But if they decide otherwise, I'll have to work out how likely a middle aged, disabled, clinically vulnerable person is to walk into another job that uses my specific skillsets outside education in the middle of a pandemic before I respond.
