It's a feast or famine industry. It's been a feast for a while, and a lot of people who are relatively new to the industry haven't experienced a famine.

My father is/was an electrician and 2008 decimated the industry. He was de facto laid off and worked part time for the better part of three years after. Of course, today there's tons of work and no one to do it. Any young'uns who came in between like 2002-2008 didn't make it through the GFC and switched careers, and the old-timers who weathered the storm don't have enough juice left to work the insane hours.
