As we have discovered with dottir's present situation , vis-a vis employment and Covid, make sure you document all communication with your company over this. i.e. send emails so they can't say they didn't know.i've just been told i've gorra go into office as of next week, even though my dad (who is staying with me) is self isolating in order to start radiotherapy next week
If there is no real reason why you cannot zoom meet etc and carry on working from home, they have to have a bloody good reason for it. Especially in your circumstances, which they must know about.
Dottir's case is going to tribunal soon. Not just over Covid but it will be part of the case.
Best of luck mate.
