I know that in SF, there are several restaurants taking planned days or time periods off because they don't have the staff to run 7 days a week, or run 7 days a week for extended periods of time. If anyone calls out, misses a shift, has to care for kids that can't go to school/daycare because of illness, quarantine, or any other reason, the inevitable trickle down effect is that they can't deliver on their service goals.
These places would rather miss a few days of work than have a bunch of angry Yelp Karens bitching and tarnishing their reputation.
As this relates to historically stagnant wages, there are other industries coming to the realization that people don't feel like the compensation reflects the work demanded. Teachers, daycare workers, low wage health care adjacent positions, etc...
What's the larger answer? I don't know. There are certainly places that can afford to pay workers more than they do, but there are also plenty that can't.
