You can help McNair Scholars in everything, from organizing seminars to working on projects, to scheduling tutors for them. It is a great learning opportunity.
No cons as such I remember.
You get what you put in. You will be promoted if you apply yourself. Education is a priority for Erie. Health benefits and pension are amazing. You won't find health benefits as good as Erie anywhere... else. Pensions are unheard of these days.
None that I can think of.
