Some Amazon workers do wear diapers when working at Amazon.
I myself am one of those Amazon workers that wears adult diapers when working because we have a quota to meat and cannot go to the bathroom often.
I have to pee a lot and so the diapers help me get through my workday without having to run to the bathroom every 30 minutes or so.
I don't poop the diaper though unless I absolutely have too.
But I do pee in the diaper and it's much better than having to use the toilet anyway.
I only work at Amazon 5 days per week and have the weekends off so I don't wear diapers when not working.
But the adult diapers make me more productive and I don't have to hold in my pee.
I do however wear adult diapers if I'm on a road trip also or out shopping because it can be hard to get to a bathroom.
Not all Amazon workers wear diapers too work but it's a good idea for them to do so.
