I strongly doubt that Amazon employees were required to pee in bottles or on people's houses to maintain their job because of scheduling requirements
Why?
Because employers are required to give employees a break every four hours
People can hold it for four hours then pee
If you can not hold it for four hours then you should see a medical professional and get a medical treatment
This is one of many reasons why hiring disabled people should not be mandatory
They should probably change the law to let them have half hour breaks once every four hours instead of once every eight hours because I do not want my stuff covered in pee
It would be worth increasing the price by one sixteenth to not have my stuff covered in pee and feces or poop
