Pros
Walgreen's has a wonderful work environment and employes a wide variety of people. I have never felt unwelcome there and have always had fun while working at all of the stores I have been to. There are ample opportunities to move up in the company; from within your home store to all over the country, Walgreen's has many job choices. The idea at Walgeen's is that it is okay to have fun at work so long as the customer leaves happy and maintaining relationships with the customer is very important. I think that anyone could be happy working there if they enjoy people's company and focus on making people happy.
Cons
The management is often not very experienced and they have a lot of turnover as management transfers or moves up, so they don't really get a lot of experience dealing with situations and policies. Also, a full-time workweek is only 30 hours, so you have to fill in at another store (which is easy to do with so many around) or hope someone calls in if you need more hours than that.
