I am assuming the governments 60 page document released today will cover this shielding/vulnerable thing : it will have to be rapidly conveyed as many workers will be expected back at work form today , once their bosses declare they simply cannot WFH!
I think a lot of teachers are a bit confused about the shielding thing as many were sent home when the original , vaguer flu jab advice came in and by the time shielding categories were created and letters sent out (some of which have only just been sent!) the schools were closed.
General union advice (not just teaching unions) is that vulnerable workers should only be asked to attend a workplace if they can be effectively kept safe : eg by stringent SD measures by an employer, and proper H and S being observed, and/or by having a front facing role changed. More anecdotally , my DH's consultant said 'when people go back to work, you will be expected back'. However, this does not account really for DH being a teacher and also,obviously, DH is not pregnant! so his vulnerability is not finite, as it were.
I am surprised there isn't a thread on this on general MN but people are afraid of being flamed and called shirkers and cowards by the 'well, supermarket workers do it 'brigade.
