I come from a small town that is dominated by chemical refineries. I know people who are electricians, HVAC repairmen, plumbers, pipefitters, and process operators. You know what scares them more than anything else in the world? A corporate policy against overtime. Many of them will pick up any extra shift they can get. They LIVE for plant turnarounds where they're basically paid 24/7 for a couple of months to essentially eat, breathe, and sleep at the plant to be on call because it's how they go financially from a lower middle class lifestyle to being solidly middle class. This is what pays their mortgages, their hunting leases, their bass boats, and the limited edition F-150 to do all that stuff with.
