Pros

The have good people within the organization. My local coworkers were good to work with.

Cons

Staff are clearly just numbers and profit centers. I was asked to work on projects (including writing government documents) where I had NO training or knowledge of the subject. The health plan was essentially a fraud. All claims seemed to be denied unless fought the denial.

Business Outlook

Pros

1) Good people who work hard 2) Flexible hours

Cons

1) Too much focus on bottom line 2) Employees are not valued at all. When the let you go you get little time to clear out your desk and the best they give you is 6 weeks pay not matter how long 15-20-30 years you have worked for them. 3) Only focus on top line growth is thru buying companies- no idea how to grow the top line- also corporate office has no idea on what the business unit really do and how they work 4) Not organized correctly-- too many silos and too bad mouthing other units-
