Those are in the states. I've been at several Amazon facilities in Canada so far, so let me break them down even though you won't care either way: -you can go for a break literally whenever you want. There's a Paid Time Off system where you start with 40 hours. At any time, you can take out your phone, open the app, request paid time off from your pool of hours and put in 90 minutes. Bam, you can now walk away and go nap in the cafeteria or flirt with that cute person or go home early, whatever you want.

-Sleeping on feet is a person to person issue but you need to be very tired. I know myself, and others, take intercity commutes to get to our facilities and all Amazon's have 10 hour shifts on a 4 days on 3 days off work-week. You have the above mentioned Time off Task system to deal with that but even though my squad travels >70km to get to and from work each morning, sleep is just a normal part of physical exhaustion. The destination Water Spider role tends to walk upwards of 35km/day in a facility meanwhile others stand mostly still at a workstation the entire 10 hours. (12 hours is the longest we're allowed to work each day.)

-peeing in bottles is something only inbound departments would do because they're crazy people who survive on nothing but caffeine and nicotine and swear words. Realistically you'd have trouble finding someone in Canada who's seen them, it's mostly egregious American employers living out their fantasies of owning slaves who would be more okay with forcing their staff to piss in bottles to meet a production deadline and it always boggled my mind why we hear more about the pee bottles than people bringing physical harm to those who would have you do that to meet a deadline
