I don't quite understand how this happens. I'm under the impression that when you are offered your job back, you have to either take it or go off of unemployment.
"In Ohio, which has encouraged businesses to report employees who don’t come back to work, approximately 600 employers have already turned in about 1,200 workers, the state’s labor agency said."[1]
Many do not. I know a fellow with his own gardening store where prospective employees refused jobs because their unemployment checks hadn't run out yet. He didn't rat them out, I doubt many did rat because the candidates were so open about why they refused the job.
My sister was able to re-open and she had the hardest time convincing her workers to return simply because of this fact.
Some never returned. Why would they?
Has nothing to do with safety or trying to keep people at home.
