They treat you like garbage.
Human beings aren't allowed to speak to each other.
Human beings aren't allowed to go to the restroom in a 12 hour shift; they say that your two 10 minute breaks are for restroom use --- that is not the law, the law says that an employer must allow you to use the restroom at any time without penalty or docking of pay. You are supposed to use breaks to TAKE A BREAK, not use the toilet.
Just another illegal operation that the common people can't fix.
Can't use the restroom in your 12 hour shift
