So, someone I work with had a positive test. I haven't been in work so I'm not personally at risk, but nobody at the workplace (a small shop) has had any notification from track and trace telling them to self isolate. Everyone has to check in on the app, so why is this? Is it that they don't have to isolate, or just the system being crap? I'm pretty sure from what I have read that anyone who's had contact with the infected person for two days prior to symptoms should isolate, and this will mean the shop closes, but nobody else seems to agree!
