Boeing

You learn an awful lot about lots of different types of manufacturing and meet people from all over the world. You will leave with a solid work ethic.

Aerospace is very volatile, and even full-time employees will experience, on average, 3-5 years of time off within a 15-year period. Therefore, everyone is always paranoid about being laid off, which makes for a stressful environment.

Ban the older people from coming into the younger folks' space every Monday and Thursday to speculate about when layoffs are coming. Seriously, everyone is paranoid and high-strung, and it not only leads to a stressful working environment but also tends to bring out the worst in people in their attempts to stay employed.
