Employers are probably waiting for the pandemic and unemployment insurance to end so they don’t have to raise wages to attract workers to these now-hazardous working conditions, as it’s hard to walk back wage raises. Every employer benefits from a society where everyone pays their employees more, but also if they are the only employer to pay their own employees as little as they can get away with. Yes, the minimum wage does need to be hiked (arguably not to $15/hour), as it’s in the best interest of both employees and workers.
