Pros
Nice Views. Get to spend lots of time in the parks. If your have any energy from being worked like a dog you might have lots to see.
Cons
Too many to list; Cronyism runs deep. Don't expect anything resembling fairness and you won't be disappointed. You can work your tail (glassdoor won't let me say the a-word) off, go above and beyond. You will not even be noticed. It's hard to understand from a human standpoint how the permanent employees can be so rude and calloused. They say they are committed to change, take that with a grain of salt. You have no rights. If you get in the wrong persons way, speak up, you will be crushed. EEO, they are there to protect the park from you and not to protect you the employee. You will probably never see anything like the dysfunctional behavior within the National Park Service. Don't let it traumatize you. It's them, not you. The disparity in pay between the people who work hard and the ones who hardly work, or are "retired in place" There is probably some NPS person reading through these reviews trying to figure out who wrote them so they can retaliate. It truly should be studied by anthropologists.
