Unless you have expressed your desire to retire at the age of 65, it is considered discrimination to release and employee for their age. Due to your longevity in this position and unblemished performance, I can not understand why your employer would want to hire and train for your job. We are not required to retire at a specific age, however, there are rewards for working until you are 70. One may take "early retirement" (62) at a significantly lower benefit than one might get at 65 and the benefit of working until age 70 is quite a bit more than the benefit one would receive at 65. Based on your 91/2 year relationship with this employer, I would think that you could speak with them and express your concern about remaining employed after your 65th birthday. This may result in finding more information about the reasoning used to justify the new hire and ease your mind. I would not threaten your employer with filing a discrimination suit if you lose your job. I believe that they are aware of the age discrimination laws and know that the fines are costly. If the reason you are let go is your age, they may chose to cover their rear-ends by not naming that as the reason.
