The advice is against non essential travel for a reason (you might think it's a personal choice but it's a selfish one) , self isolating once you are home isn't a magic eraser, you are still on a flight and passing through an airport, standing in a baggage hall, and possibly getting in a taxi/public transport/ getting a lift from the airport... All of which is time you could be spreading the virusI work on the same floor as jens journey and Dominiques little sister. Jen isn't back in work for atleast another week. Im not sure if she went away last week but if she did she is probably isolating now and she's back since Sunday evening or Monday morning on stories. I went to Spain last month and had to fill out a form and they check up on you. So I was 2 weeks out of work unpaid. So long as she self isolates for the 2 weeks I think it's fine. She's following protocol. She probably didn't share on stories she was there because she had been saying for ages she wanted a social media break and probably didn't want to rub it in people's faces that didn't get away. Countries on red list just mean that you need to isolate for 14 days after. It's not illegal to leave and trave to those countries. I think it's a personal choice if you know you're going to stay safe and be smart.
