Pros

Hired as a "fire-hire," the position is disaster based and 100% travel so you get to travel domestically paid for by the company. When working, pay is good, you can make a lot very quickly with overtime. Being part-time, I can take time-off whenever I want for as long as I want.

Cons

For my position, no natural disasters = no work. Living out of a hotel for months SUCKs and burn-out is real as you could be working 7 days a week, 12 hours a day for months on end. There's no added compensation for taking on an on-site lead position even though the workload triples. As a part-time employee, you have to pay more for benefits when working versus not working. There's a huge disconnect between part-time employees in the field and the full-time employees that do office work and upper management. Part-time workers are not prioritized unless they're willing to do whatever is thrown at them without complaints. The employee turn-over rate in the field is crazy.
