Wal-Mart is great for those able to adapt to constant change; if not, find a different industry to work in!
Pros
Job security and career advancement are two of the top reasons although their are many others that aren't truly realized until you are a part of the Wal-Mart family. It's important to realize that Wal-Mart is really no different than any other retailer when it comes to stress and wages. Each Wal-Mart store is its own family and, as in life, some families are dysfunctional while others grow together; this is why it's also important not to point a finger at Wal-Mart as a company when a specific store is having problems. Overall, Wal-Mart is a great company to work for! By the way, it's also worth noting that Wal-Mart associates receive quarterly cash bonuses of up to $450.
Cons
Stress and poor communication that leads to additional stress! It's honestly difficult to think of a true downside that is exclusive to being with Wal-Mart. I guess the only thing is the inability for many of the long term associates to adapt to changes currently underway at Wal-Mart. Again, though, this is not a problem exclusive to Wal-Mart, all retail chains must change to adapt to changing times in the industry. It's the companies like Circuit City that fail to implement change year after year that are destined to fail. I feel more secure working for a company that is always changing than for one that continues to do the same thing year after year!
