You dont have to pay them.
We have had this situation at work. Oddly from a man whose partner is a nurse. So far more likely to catch from her than a keyboard.
Brand new equipment, only taken out of packing to be sanitised. then put in sealed clean bags to be dropped off.
He is now on unpaid leave and of course wants to actually work from home.
Unfortunately, he was out on unpaid and his equipment went to someone else, he is now back of the queue. He will have it by tomorrow at the latest. But several days unpaid.
If he then becomes sick, he gets ssp (presuming you dont pay full sick pay) for 2 weeks.
Theres absolutely no reason, wether he lives with some vulnerable or not, he can not have the equipment in the house.
He cant have the 80% of wages from the government, because you have work for him to do.
Bet when he realises its unpaid, he will try sick leave. Unless that's for full pay, he will start working from home.
