Vantaggi
There are some amazing people, but they are few and far between and definitely not in management. ESOP is the only other Pro.
Svantaggi
Nepotism, good ol' boy clubs, cliques, micro management, bullying, sexual harassment, management gossips about their direct report's personal business, management expects you to sacrifice your time in order to "prove yourself" or "make a name for yourself". There are no standards and every project manager does everything different. There's no genuine people in management, not people that care about anyone other than themselves. Managers dump all the work onto their APM's and PA's and then get frustrated when there's a backlog, meanwhile they spend most the day gossiping and bullying their coworkers and trade partners.
