Other than Cat or Deere I was unaware that any retiree health coverage existed. Gonzo for most Americans, and has been so for at least a decade.
I clearly worked for the wrong employer(s) my working career.
Maybe of the legacy technology companies (like Hewlett Packard and IBM) have retiree healthcare. But, they are starting to phase it out. I know someone that is retiring at the end of this year because her employer is ending retiree health care for people that retire starting in 2017.
