Pros
Grameen Foundation has great people, a great mission, and a cool history. It has historically had great work/life balance and flexibility, though in 2016 those perks started disappearing. Its leaders care about the work they are doing and strive to do it well. Lower level staff are amazing - keeping the place running despite strategic confusion, inadequate staffing, and poor internal communication.
Cons
Grameen is top-heavy. There has been effort to slim down the number of senior leaders pulling in bigger salaries, but the pendulum swings back to the top-heavy side pretty quickly. Meanwhile, there are far too few lower level staff to keep the place running smoothly. Far, far too few. And the pay system for these lower level staff is confounding. In some departments, you are likely to be paid fairly in relation to your talent and productivity. In others, you may be paid way less than market rate for your skillset even if you are a top performer. Obviously this leads to low morale, high turnover, and consequently the exacerbation of problems around staffing. It's hard to make money for an INGO these days, and Grameen is not immune to the hardships, but in order to be the lean org it pretends to be, it's got to stop hiring "big thinkers" who don't want to roll up their sleeves.
