Yes, I think I clearly suggested it's down to government and facility administration, although I referred the industry as a whole.
The story notes all but two people walked off the job. I'm certain the two who remained are registered nurses and the rest are PSWs, as that's how these homes are staffed. Absolutely not the worker's fault this happened. They're not in violation of any law by protecting themselves. PSWs have very difficult and unpleasant jobs, are poorly remunerated and are in environments where they're currently at very high risk of contracting a disease that could kill them, and has in a neighbouring province. The facility's administration should shoulder a lot of blame, some of which they can share with the government. This didn't happen overnight.
The pay of the people who walked off the job is important to the debate because, as noted, they often work at more than one facility, which has contributed to the spread of COVID19 among care home populations. If they only had to work at one facility the problem in this very specific demographic wouldn't be so bad. That's a combination of workers making low wage and a lack of workers, but the lack of workers is also influenced by the rate of pay.
