That's why people work hard to acquire skills, to be able to work in better jobs.

I have never run a warehouse, but I suspect that many of the strange seeming rules are in place because people otherwise try to exploit the system (like getting paid for smoking on the toilet for hours on end). It may seem inhumane, but perhaps it makes it possible to give people jobs who don't deserve automatic trust. Such people exist, unfortunately.

I found very interesting the book of the guy who founded "The Big Issue", a magazine that homeless people sell in Britain. They also had to put some rules in place that seem strange, for example the vendors (homeless people) had to buy the magazines they wanted to sell. They are alcoholics, gamblers, addicts, so unfortunately some special rules were necessary to make it work.
