If you’re still unwell after your 10 days isolation but your work we’re expecting you back, were you able to get a sick/fit note (not sure what they call it these days) from your gp?
What did you tell them about your symptoms and did you have to go in for an examination? (Don’t want to risk catching something else!)
I am not sure if they’ll automatically issue a note or if it’s something you had to fight for?
