Pros
Target offers a fun environment, at least in comparison to similar types of stores. HR is very reasonable with hours and scheduling and there is a great degree of flexibility in determining your work schedule. The 10% employee discount is great- it definitely adds up in savings over time. There are many employees from highly diverse backgrounds, leading to a rich work experience where it is very easy to make friends and meet new people. You can also learn a great deal about the retail business if you monitor your surroundings and soak everything in. Overall, I had a decent experience, but would not recommend working there for more than a few years.
Cons
The job can get very tedious and boring after a short amount of time. People have different schedules, which means you can have a wildly-varying work experience each day you come in to work, which was for me, mostly a bad thing. Very few fellow employees are motivated, meaning the bulk of a project can fall on your shoulders. Customers are very likely to take things out on you and get angry with you, which can have an effect on you over time. Also, you are on your feet for the entire day with only a few brief periods of rest.
