Pros
Benefits package is awesome. (At least in the union shops.) Guaranteed full time work. You can accrue up to four weeks paid vacation within one year.
Cons
Unless you're seriously down and out and just need a job to scrape by for a few months, or someone with no office experience or just out of school, then I suggest you turn and RUN not walk the other way. For the data entry position they generally hire on about 20 people. By the end of your initial training, expect as much as half the class to have been canned. Then of those who get to advance to the floor, expect at least half more to be gone by the end of the 120 day probation period. Within a year, it would be astounding to see even one of those 20 people still working there. In my opinion, this is horrible business practice. Wouldn't it be better to hire 5 people, of whom all are very qualified, and then train them correctly (so you won't have to fire them in a few months) and pay them a living wage so they want to stay? The environment is hostile because you're constantly being told that you'll kill someone's grandma, it's extremely stressful because they expect you to pump out 30 scripts an hour which is inhuman if you're going for complete accuracy. I lasted a month before I became so stressed out at work that I felt I couldn't perform. Seriously, unles this is your breakthrough into the medical field or the administrative field, don't even waste your time. Chances are, you won't even make it out of the first three weeks. Good freaking luck.
