I think it's a great idea for Amazon workers to be wearing diapers as it means they can just go pee or poop when needed in the diaper and not have to hold it in.
If I worked at Amazon I would be wearing diapers while working because I wear diapers all the time now.
I no longer us a toilet and have not used a toilet in over 8 years now and plan to use and wear diapers for the rest of my life.
Diapers are much better to use than a toilet because you don't have to hold your pee in or poop in and look for a toilet.
The diaper is your toilet and it's a great thing.
I only go into public bathrooms now to change my diaper but no longer use the toilet.
Wearing and using diapers is much healthier and more hygienic than using a public toilet ever would be.
