Pros
The aim of the foundation is to deliver on the belief that everyone deserves the chance to live a healthy and productive life; as an employee, all of your work goes towards this, even if it may not feel like it every day. I'm so proud of the organization, my time there, and the effort of so many creative passionate coworkers, not to mention the impact on millions of lives, now and forever. You're part of something bigger than yourself and that's tough to beat.
Cons
The foundation has gotten much larger over the years. Its giving has also increased substantially, both in terms of amount and geographical distribution. As such, I think it has become more complicated to get things done inside of the foundation. The organizational processes haven't quite kept pace and I think people don't necessarily stop to improve, but instead work harder to get things done. I don't think this is very different from any other growing organization. Leaders, along with staff, are actively focused on improving this.
