Where does the money come from? Is it that they don’t have to go to back to work because of the rent moratorium? At some point you have to buy food and pay the utilities. What else could be stopping people from going back to work?
Also, people are just ending up homeless. Going back to work costs a lot of money. Car payments, gas, insurance, tickets, parking, registration, and tolls. Sometimes people just don't have the resources to do that.
I wouldn't be surprised if a lot of the issues with missing employees is a lack of transportation rather than lack of people wanting to come back to work. Used cars are hard to find and super expensive. Public transit is mostly shut down or non-existent. Even motorcycles are selling out. A dealership I visited recently started bringing in used motorcycles onto the floor that they would normally keep outside because they couldn't keep new ones in stock.
I've had one friend stuck riding his bicycle 30+ miles a day in 100 degree F weather just to get to work because his license is suspended from unpaid tickets. Another is borrowing my car because he can't get one himself and he's going to be waiting 6 months on a motorcycle. My partner is riding his bike as well for 16 miles since he can't drive my truck.
