Pros
Walgreen's has been around for over a hundred years and is still building about 500 new stores a year. Very seldom does the company close stores or lay off employees and sales are up every year. This is a very important consideration in lieu of recent economic events that have led once healthy organizations to fold because of credit problems. Walgreen's seems to be almost immune to the current credit situation because the company runs on zero to little debt. Salary compensation is fair for the most part, especially when you consider how small the stores are that a manager is running. Benefits are better than most with a 401(k) match of 3:1 plus a stock purchase discount of 10% off market value. The company looks to promote from within so if you stick around and hone your skills the future can be very bright for you.
Cons
For me working nights, weekends and holidays has started to get very annoying. It's an understandable necessity in this industry, but when I was in college and never thought I'd be working retail as a career. The schedule is much better once you are promoted to store manager, but that can take anywhere from three to seven years to happen, if you get promoted at all.
