Good starting place - Graphic Designer The UPS Store Employee Review

Nice bosses, good coworkers, predictable work

Stressful or rude customers, busy days

It's a job. More pleasant and cleaner than fast food for what it's worth. Small business environment (since most stores are franchised) may either be a blessing or a nightmare depending on the owner(s) and management.

Extremely hectic and high-pressure work environments. Job responsibilities are more or less everything to do in such stores. Experience can vary wildly by franchise management. Arguably greater work stress and responsibility than comparable retail jobs for significantly less pay.
