Pros
American Express promotes an incredible work / life balance. Some areas have flexible work arrangements, allowing you to work from home. Their vacation time is extremely generous, and corporate culture is incredible. The company is a leader in diversity, and everyone is respected. Promotions are possible, and the company highly regards promoting from within.
Cons
With the loss of Costco, the company has downsized A LOT. The CEO reaction to poor leadership decisions, or a dip in the share price, is to lay people off. While the corporate culture is phenomenal, the company hasn't kept pace with younger consumers, and is losing market share. High performers are leaving in droves and finding places to work, that are more profitable. It's no longer the company that it used to be.
