Older workers: Empty nest (kids out of the house, can put more into work if needed), decades of experience, with VZ for decade(s) so would have already been canned if they were not good at their job (recall VZ had 200K+ fulltime employees 15 years ago or so)... Why would you kick them to the curb when they are in arguably the most productive years of their lives?
Short sighted id--ts in leadership positions. Its like not maintaining your vehicle to save a few buck up front. But, I guess leadership plans to not have an interest/stake in the car (VZ) in the future.
