The VSP simply is not good enough to get the wanted numbers. People with Under 26 years basically don't have pensions so they only get a little over a year salary so it is worth staying and the risk. Prizes offer a VSP that pays 3 weeks for every year service with a cap at 110 weeks I believe and insurance for 3 years. If that was offered at Verizon then they would certainly get the wanted numbers to leave.
400 techs under my 3rd level and 2/3 of them need 2-3 years on time and service to be able to roll out but if offered roll out they would.
