Assembly line jobs are rough and people pee in bottles, and die. The important piece these articles leave out is how much more common these are at Amazon.
I remember my first jobs at random companies where I was hourly and needed approval for bathroom breaks. It sucked and I would plan my day around break times.
I think these articles are more a function of being surprising to us because we work cushy desk jobs where we can break all we want and use unlimited sick days because we program.
