Vantaggi
This is specifically for working in the warehouse portion of a distribution center. Staying in good physical shape is NOT an issue when working at UPS inside one of their distribution centers. Even working part time, 3-4 hours each day, the level of physical activity is pretty extreme. Yes, this may sound bad to a lot of people, but if you're interested in staying in shape and getting paid, this is a great way to do it. Oh, and uh... good team environment, stable pay, and the company is willing to adapt to your physical abilities - if you can't do something crazy (like unload a shipping truck in <10 minutes) you can do something more suitable. If you want more work, they provide the option to assist the drivers with making deliveries. This extra work, coupled with morning warehouse work, can turn UPS into a (almost) full-time job (with a pretty long lunch break). This is great if you want to travel locally, meet new people, and train to move up within the company to a driving and delivery position. But you have to wear a uniform.
Svantaggi
Again, the physical activity. This work is not for the medically challenged, the elderly, the asthmatic, or the lazy. Speed and strength are essential. Although safety is a prime concern, it is very easy to injure yourself or others through careless mistakes, improper lifting techniques, communication failures, or being over-ambitious when lifting and moving packages. Some of the packages are awkward - stacks of tires, broken boxes of printer ink cartridges being sent for recycling, bags of golf clubs, 12 foot long 2x4 blocks of wood... UPS will ship pretty much anything that's not alive or illegal. The pay and benefits aren't that great - but they are better than what you might expect from a part-time job.
