There are a lot of negative aspects to working a job such as this that some people find hard to accommodate. Social life is non-existant, workers and coporate are spiteful. It is overall suffering for the greater good, and I've seen a lot of people unable to handle it. My sick self, however, loved it.
Short breaks. Long hours. Hard to get days off. No room to advance. No time for family. Sleep, eat, Jeep.
