Pros

The benefits are decent but not great and the people you interact with directly can be pretty good.

Cons

Over-complicated systems stringed together. Not everyone is responsive or held accountable.

Business Outlook

Pros

Very large company with opportunities for upward movement, if you are good at politics, and can talk your way through a spreadsheet; sprinkle in some six sigma principles to cover up mistakes - results are measured through likability, and NOT accountability. Sales driven environment, but be careful with comps, as they are often decreased to make up for regional losses....

Cons

Operations is a chase after your own tail environment; Chaotic, Erratic, Drama field, which is extremely disorganized, and reflects on the quality of patient care and service. Still managed from the Top down (zero leadership or accountability) at the exempt levels - non-exempts work more with less, as there are too many subsideries to effectively support in an 8 hour day (if you are lucky to work an 8 hour day), Fear of reprisal is deeply imbedded and encouraged to influence production. Benefits are rapidly changing to make up for poor financial forecasting, attrition, and lack of reimbursement from United Health Care.

Pros

Short distance from home to work. Near different gas stations and restaurants for break.

Cons

Low Pay. Immature work environment. Too much overtime that is told from management at the last minute. High Turnover. Will hire just about anyone without a felony. If you are desperate and in need of money, apply. However, don't get too settled because once you're in you'll never want to leave and then you'll be stuck. Stuck year after year with no new title or growth.
