“Essential workers” is a nebulous term - formally there are only “essential businesses” that are allowed to operate, and their employees are informally “essential” too. But only a subset of such workers are necessary. E.g., cleaning staff at hotels might be called “essential workers”, but if the hotels are virtually empty most of those workers aren’t needed. Granting extra UI benefits allows the employer to determine which workers to keep, and compensates those actually laid off to avoid unexpected hardship.
None of the essential workers mentioned in the article lost their jobs that I can see. One was just temporarily overpaid for taking an otherwise unpaid leave. They stayed home, and received more pay for doing so. The fact that the UI bonus encourages this behavior (within the bounds that employers tolerate) is exactly the social benefit I’m pointing out in my original comment — the UI benefit encourages people to stay home if they can.
The workers in the article are complaining about the unfairness of not receiving extra pay, and justifiably so — it is unfair. The UI benefit helps slow the spread of a deadly pandemic (and mitigates foreseeable bankruptcies/evictions) while also making the world less fair for the people who are still employed. The article only discusses the latter, and I was pointing out the former.
