Pros

Not alone going for it right now. Every midwest office is struggling with work

Cons

Forced to use PTO when no billable work is available. PMs guard work and play favorites to who they distribute to. Raises are abysmal. No employee gets higher than 2% due to how profits are split company wide between operating units. Medical benifits were diluted to just Aetna and has higher premiums after having several options the previous years. DEI language was stripped from the company to satisfy the current administration.

Poor Work-Life Balance

Environmental scientist

Business Outlook

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.
