Pros
Unlike many companies, you won't really find employees here who do much less than everyone else and always "slide by". Everyone who works there works incredibly hard and is held to a high standard. If you're interested in a career in the non-profit industry, being able to list GG+A on your resume will help you land jobs at non-profit institutions. The time off allowed is pretty standard, and they don't usually give you a hard time about when you can schedule your vacation. They also keep the office stocked with free soda to keep everyone caffeinated.
Cons
Everyone seems to be dissatisfied. The owner's dissatisfied that he's losing money; the consultants lead hectic lives and are dissatisfied with the way Management handles things; the small office staff is dissatisfied with the growing demands placed on them and the stifling atmosphere; and the clients are dissatisfied with the deliverables they receive. The firm demands all of its employees' time, and most employees are not able to have a family life. Even worse, the company had recent layoffs that eliminated several positions that were responsible for large amounts of work, which of course increased everyone else's workload, while simultaneously cutting the salaries of the employees that remained. People routinely walk out after short periods of employment purely because they are fed up. I knew within the first week of working there that I had made a bad choice, and I should have listened to my gut.
