The isolation rules are no longer fit for purpose.
My partner & I are both double jabbed but are on day 7 of a 10 day isolation, as we were in contact with someone who tested positive. We have both taken PCR tests since and they are negative also. I work from home but she works for the NHS doing work that is life or death for some people. Half of her team are isolating which means that the service they provide is compromised.
I think in the coming weeks lots of people will be getting pinged to self isolate unless they change it. I'm sure I heard something about it changing in August and that you might not have to self isoltae if you are double jabbed by then, but I think the next few weeks until then could be absolute chaos.
