Vantaggi
Working at Shaw's is a decent way for a high school student to earn minimum wage to support basic entertainment like movies, concerts, etc. The work takes absolutely no thought at all, and that can be a good or bad thing. For me, it was a bad thing... but several of my employees were perfectly content bagging groceries, sorting bottles, and pushing carts, as long as they were getting their money. But really, you can't expect significantly better if you are just a high school kid looking to earn some money over the summer or on the side of school.
Svantaggi
The management is horribly disrespectful. There is absolutely no opportunity to give feedback as to how things could be done better, etc. It's totally mindless work which drives a creative person like me crazy. I just felt like my mind was going to waste doing incredibly boring tasks. You have to deal with customers all day, some of whom are rude but most of whom are at least tolerable. But when you try to joke around with them and lighten the mood, the manager gets upset and tells you to "take your job more seriously" or "get back to work"--what happened to the human side of business?
