I thought I'd posted here, but must have been a different thread.
Our local carehome looked into this with social services and lawyers a long time ago. Obviously they are not intending to make the jab a requirement- they know more than anybody, about human rights, laws, consent, coercion etc, but needed the answers in case anybody asked them.
They cannot make it a requirement, as it comes under discrimination laws and somebody would only have to say it was against their beliefs, to have no hope.
In any case, it wouldn't be practical, because they can't afford retraining, inducting, and qualifying of all new staff, as well as needing experienced people to work alongside them. And if it was a requirement, it would have to involve everybody.
