If I was running a warehouse, I would certainly let truckers use the bathroom, for heaven’s sake!
Nope. The DOT issued a regulation that truckers couldn't use local bathrooms in the building "to stop the spread of Covid".
We had to put yellow tape across the doors.
But they could use the bathroom at the local truck stop 10 minutes away.
It wasn't the warehouse owner, it was the feds (sometimes the state) and the HR depts of these massive warehouse companies that pushed the rules.
When the subject of drivers having no access to bathrooms at customer locations comes up in a conversation I always give the same answer:
“I know quite a few shippers who used to let drivers use their bathrooms. They stopped allowing it when they got tired of cleaning up after a lot of strangers who have the personal hygiene habits of illegal Mexican immigrants sleeping under an overpass in Southern California.”
