MY TURN (I GET THE AX TODAY)!

Pros and cons to filing at 62. You only get about 75% . However you get your money four years earlier.
Now if they have eliminated or combined your position then there's not much you can do, but as someone else said collect comp. And move on. If they hired a younger person to do your job then that's age discrimination.
I would then get a lawyer involved. Whatever road you go down best of luck to you.
