Correct, they are betting that unemployment benefits and eviction maratoriums will end and the workers will come back. They don't want to get locked into higher labor costs. Some businesses genuinely can't operated at a higher cost price as well
I'll believe that when executive pay at said companies isn't high enough to cover hiring 1000+ front line workers that they supposedly can't find.
Their CEO alone made $14m last year and their wages are $15-33/hr. "Can't afford" isn't the issue.
