I like Ann Bares' posting on "Should Rewards be Tailored to Generational Differences?" She says "no" and offers thoughtful commentary why. She also self-discloses her bias:
"I am a Boomer and admittedly prone to thinking that we get a little carried away with all this generational difference business. My life experience suggests to me that we're all different ... and similar, and that we all share characteristics with many peer groups - not just generational, but gender, religious, geographic, occupational, recreational/hobby/dining preference, etc."
I am NOT a boomer, but I agree with her perspective and offered a comment of my own for her to consider. You can read the full posting and comments here.
