Pros

Option to work from home if you’re ever given reporting work. Lots of opportunities to learn new sampling and monitoring skills. Wide range of equipment to become proficient at. Helpful coworkers.

Cons

Barely any local work and you’re expected to constantly travel, which was not explained well prior to hiring. OT is paid in straight time, not time and a half. Salary pay has no benefit because if work is unavailable, you’re expected to pull hours from your PTO to cover your 40 hour/week billable requirement. You have to practically beg for work to be included on projects. There is a lot of favoritism that results in other people getting more desirable projects. If you’re on-call, you only get 6 hours to bill for calibrations/readiness even though being on-call requires you to stay local and miss out on guaranteed hours by traveling. Supervisors are generally unhelpful when it comes to career development. Mandatory week long yearly training that you have to travel for.

Pros

Management was super considerate and forthcoming during federal funding cuts, and they pay better than most international development jobs.

Cons

Time off policy is not great, and takes a long time to earn more. The 401k also requires 5 years to fully vest, so between the two you earn limited benefits until you have been there for 5+ years.
