I don't understand why firms don't wait a bit until numbers go down and more people vaccinated. I should think most forward-thinking firms would do a hybrid-model, for where people can work as efficiently at home, so that there is cohesion, mentoring, f-2-f interaction etc, but aren't making people come in just for the sake of it.
Some firms really do seem to want to bring people in just for the sake of it.
If they can't have normality, they want the illusion of it, however briefly. 
I don't want to call people idiots, but some bosses are more clued up than others.
I'm very lucky that mine saw Lockdown 1 coming, saw the second wave coming, and now knows it's ours to lose again, like it was last summer. If we mess up there'll be a third wave. And a fourth if we don't get a grip.
Unfortunately this government has messed up almost everything about its pandemic response. It will be studied forever as an exemplar of what not to do with some of the best resources on the planet. So it's pretty difficult to have faith that they'll steer a sensible course this time.
But third time's the charm, eh?
