@woomy and any others that liked the response, I'm not saying it should be done on pie in the sky
Given what we currently know about COVID-19 and the Omicron variant, CDC is shortening the recommended time for isolation from 10 days for people with COVID-19 to 5 days, if asymptomatic, followed by 5 days of wearing a mask when around others. The change is motivated by science demonstrating that the majority of SARS-CoV-2 transmission occurs early in the course of illness, generally in the 1-2 days prior to onset of symptoms and the 2-3 days after. Therefore, people who test positive should isolate for 5 days and, if asymptomatic at that time, they may leave isolation if they can continue to mask for 5 days to minimize the risk of infecting others.

Now I think 7 days as it currently is, with successive negative lateral flow results, is pretty sensible. But going into lockdown doesn't do anything to stop healthcare workers having to isolate, given the abundance of evidence that COVID is being spread more in those settings.
So the only thing that can be done to stop key workers like that needing to isolate is to... shorten the amount of time they have to isolate?
