Pros
Actually, the pay was fairly high, considering the area, and the skills and education of the people doing much of the work - too high, actually, in many cases.
Cons
Most of the people there were nearing sixty, and had never worked at another job in their lives. They graduated high school and came to work there. They were xenophobic, jealous of their legacy knowledge, unhelpful, unschooled, and not terribly interested in making their process or their product any better. The middle management was recruited from those who were good at doing the manual labor, and there appeared to be no other requisite for those positions. Promotion from within does not work if those promoted are not qualified. The entire culture of this facility was a holdover from the 1950s; xenophobia, paranoia, fear and distrust of anything new (especially technology). Employees commonly sabotaged one another's work in hopes of coming to favor with their supervisors.
