Compulsory self-isolation is ending if you test positive with covid. Instead, people are being advised to choose to self-isolate.
In reality, I think many people will not. I would not get paid if I self-isolate but am well enough to work, so why would I forego a week's wages?
So will you self-isolate if you test positive with covid?
YABU - Yes I will self-isolate
YANBU - No I will not self-isolate
