@Dyslexicwonder same in our Trust - our 2020 Christmas do was on Teams. We got funding from the Trust charity for everyone to be sent a small parcel of nice things to their home - some biscuits, hot choc and so on. Please note: no actual NHS funding was spent on this. People ran marathons to rise the money to pay for it.
A lot of people, myself included, went to a lot of effort on our own time to have an event that would work online and it was pretty good. But don't bloody tell me we were having parties with cakes and sarnies in staffrooms - and yes, clinical staff were included.
