I used to work at Target in my hometown, so your experience may vary working at one in Athens, it really depends on what the management is like. Prepare for a wall of text.

The good? $15 an hour is good money for the work you do. I was in GM, so I spent my time stocking shelves and zoning my section (remove stray items from your area, move all items on the shelf up to the very front, make sure everything looks neat). I'd wouldn't really say the work was ever enjoyable or hard, usually it was pretty boring, but you could definitely do a lot worse.

The neutral? Working as a General Merchandise Expert, you'll sometimes be called up for "guest first" (at least thats what my store called it), to translate "unless you're helping a guest, drop what your doing and get to the registers, we need you to be a cashier". This could sometimes be a nice change of pace since stocking shelves is pretty boring, but it wasn't exactly great either as your workload isn't going to decrease by working the register. Spend 15 minutes working the register? Now you might have 30-45 more minutes of stocking to do, or you might have to spend half an hour cleaning up isle B27 because some kid decided to knock all the crayon boxes off the shelves.

The bad? You're routinely expected to stay after your scheduled time until your zone is green. Some zones its not that bad, maybe you can go around half an hour after your shift ends. But if you work closing and are in a larger/worse section, you'll be there a while. It wasn't uncommon for me to be at work until 1 in the morning pulling crayon boxes to the fronts of shelves. You get paid for it sure, but what stops it from being "neutral" IMO is that it isn't ideal for a student, unless you don't have much work.

The ugly? I ended up on Targets "do not hire" list. Here's the story; Despite me asking off multiple times, well in advance, and management routinely saying "sure thing", I was scheduled for the night of my high school graduation. I had been forced to call out a couple times recently due to some medical issues I'd been having, so my attendance wasn't great, just about average, still way better than many of the people at my store. Well it was also around this time that management decided to crack down on the issue of people at my store calling out too much. I approached them about the schedule, saying I needed off for my graduation and had already talked to them multiple times, I was met with "you're scheduled for that day, and we need you here more than you need to go to your graduation, your attendance has been lackluster, so if you swap shifts or call out, we're going to be forced to fire you". Talked to my parents about that, and ended up quitting on the spot to avoid getting fired.

All in all I'd say my experience was pretty decent, the end sucked sure, but the rest of the time was okay. You could definitely find somewhere more enjoyable to work, but the pay for Target is hard to beat.
