As a former Amazon delivery driver, I can confirm you have to piss in bottles when driving for them. I still have a dopamine rush when I drive past a neighborhood construction site with a Porta potty.

They're being sneaky as fuck with their wording in those tweets though.

Technically, the people peeing in bottles in the back of vans are not their employees. They're employees of the Delivery Service Provider(DSP) logistics companies that they contract with. Which means they're able to say "Our employees do not have to pee in bottles, blah blah they get health care, blah." Their employees don't.
