Unitedhealth started outsourcing years ago.
I was there thru it all.
Of course it was then kept quite done on the hush hush.
I watched and I mean I was physically there seeing my coworkers friend's being let go.
I was given the opportunity to go to the Philippines for a very hefty amount of money to train and I refused that so called "opportunity".
United has outsourced/offshored a lot of positions, this is true. However, the company does offer a wide variety of other positions. I would suggest that if you are in a position that is easy to outsource, take advantage of the company policy that allows you to move around. Retrain, and make yourself valuable.
Please note I am not in HR or management, and do not speak for UnitedHealth. I have just seen first hand that they do offer career mobility if you look for it.
