They are, to paint with a very broad brush, folks who all worked in food service, retail, or other front-line sales industries. The forced time off last year made them realize they were killing themselves for not very much money, and they're refusing to go back to those employers.
But it's the $300 in weekly payments that is stopping people from returning to work, if you ask business owners in the area.
There is currently a wild and IMMENSE disconnect from worker attitudes to beliefs about worker attitudes, and I don't know why.
