In well over a decade of working at Verizon I have had only two bosses out of at least eleven that understood how to challenge, develop, and support their direct reports. While managers go through training I do not believe that most really understand how to be a good leader.
Verizon was a very generous company to its employees but over the last eight years it has changed. Executive and stockholder interests have pushed the employees toward taking less and less of the gains from productivity and growth. Verizon has had two layoffs in 2015 alone (one was very large) and I would expect there to be more pressure to drive down costs by eliminating positions in the future. Verizon has also restructured, reclassified employees, to hourly workers demoted employees, and is hiring more non-employee contract workers to lower employee costs.
