A positive corporate life, the legacy of Sam Walton, and loyalty to their associates
Pros
The best part about working for Walmart Stores, Inc. at the corporate level is their commitment to and investment in their associates. Once you are a part of their family, you are there to stay—so long as you work hard, of course. They provide a number of personal and otherwise growth opportunities, many at the company's expense, and the legacy of Sam Walton looms large (and this is a very good thing). A very friendly corporate environment, executives that are not "above it all," and a regular celebration of both associates and company success.
Cons
It can be difficult to advance in the company past middle management unless you have the right connections or fit the right HR profile. Compensation raises at a slow, trickling rate unless you change jobs (which can only occur after 18 months in your current role). This results in an odd environment where most people have been doing their job for less than 18 months—not exactly the best way to maintain consistency across the board. This also damages relationships with third parties and suppliers.
