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.

Pros

Not any that I can think of

Cons

So many to be honest. No room for professional development especially at a junior level. Be ready to do whatever is dumped on you whenever. On top of that, benefits and pay are absolutely awful. Pay is way below market, only offer 23 days total of time off including holidays to any new employee regardless of experience. And no paid maternity leave. In 2026! It's just one degree better than being unemployed if you have an advanced degree.
