Pros
If you like interacting and helping with customers, then a job at Target is suitable for you. The environment is quite pleasant, with a nice tea-room. Most managers are quite laid back with how you do your work, as long as you are getting the job done and aren't stuffing around. A good mix of people, I made a lot of great friends from my Target. Quite easy to take time off as a casual and get out of shifts.
Cons
Management can get very picky about the smallest things. If you are a casual, expect to get hardly any shifts in quiet periods. Expect to get some of your shifts cancelled occasionally as well. There's only so much you can do to help an angry customer; an example is when they have lost an item they had on hold and there was only one of them left in the store.
