Pros
Great benefits, generous retirement contributions, excellent Paid Time Off accrual rates, worthy mission, and passionate coworkers.
Cons
PHI programs are essentially autonomous and there is no real oversight of program leadership. Program leaders are technical experts but often lack the necessary training to effectively manage people. My former managers ignored PHI policies and procedures, were willfully ignorant of state labor law, and regularly invented new policies that only applied to particular members of staff, wth loop holes for management and specific "favorites." In the case of my previous program, one particular manager regularly bullied, belittled, and intimided members of support staff on a daily basis and repeatedly made unprofessional comments that were ignored by the program's PI, as well as PHI central. The environment at my former program became so toxic that I had no choice but to look for a new opportunity.
