Pros
LLS has a great mission to, unlike many cancer organizations which focus on awareness, prevention, etc, focuses on funding research and clinical trials to find cures for blood cancers. The national organization's unrelenting focus and achievements are admirable and due to the work of many passionate employees. I encountered many kind and super motivated people in my time with LLS.
Cons
The company culture was toxic, cliquey, gossipy, and snide. Senior staff would cut staff members short, visibly roll their eyes and shut down clarifying questions or comments in meetings. Employees favored by senior management were united in trying to isolate some managers, laughing openly that they would be fired in short time. Often new employees would find that they were either "in the club" or not quickly. Those who weren't would have their performance picked apart, each apparent flaw used to justify their bad fit with the organization. It was a sad, alienating place for some and a cool, hard-nosed New York City power position for others.
