Former UHG tech
UHG bought Oxoford Health Plans while I worked there. UHG is nothing short of evil. They fired call center people unjustly every year (slow call season) so they wouldn't have to pay unemployment benefits. They prohibited social activity at work (couldn't even put up for sale/free adds on the share boards anymore) they skimped on basic service desk support (1 tech per 700+).
From what I learned inside without giving up detail - they would rather people die than pay benefits due, and that was common.
In other words - Karma found a way - to bad the super greedy evil executives will never have to pay a penny. Look them up, you will be disgusted too.
