Can anybody avoid self-isolation when told to isolate following a positive covid-19 test in their bubble at sixth form? I am aware of someone who is not isolating until next week following a negative covid test: saying that they don't need to according to NHS 101 (they didn't tell them they were a direct contact of someone), so my employer is taking this advice as final over PHE and DofE telling this person to isolate.However, I have been told that a test doesn't allow you to get out of quarantine if you have been a Covid-19 contact. Feel like my employer isnt taking the issue seriously enough and that I look stupid for saying this person is not meant to be at work, putting others at risk.
