Provinces' new healthcare plan seems totally illogical

I'm no health expert but, from a purely logical standpoint, Quebec and Ontario's latest plan seems like a particularly daft idea. 

Desperate to keep as many healthcare staff as possible on the job, both provinces are apparently considering mandating that infected but asymptomatic health workers stay at work, even as they continue with daily self-testing. 

I understand that the provinces need all hands on deck at the moment, but this seems like a particularly short-sighted and counter-productive plan. Surely, in the era of Omicron, it will just lead to more transmission within the workplace, and more and more people infected, some of whom will be asymptomatic, but some of whom will be symptomatic. So, the healthcare sector will lose even more active personnel, and the provinces will be in a worse situation than ever.

Am I missing something?
