As a Warehouse Associate, I don’t really have much insight into TD as it applies to my organization, at least not on the executive level. However, I have noticed that many of my coworkers are over-qualified for the positions they currently fill.
For example, my supervisor is a fellow Phoenix with an AAS degree in IT, and there are numerous veterans in clerical, supervisory and equipment operator positions that are likely well below the skill level they obtained during their military service. The one exception would be our Facilities/IT Manager, who currently serves as a Drill Instructor in the Army Reserves. In addition to being the IT Manager, he’s responsible for overall safety, as well the Security, Custodial and Maintenance departments. If anything, I would say he has more duties than one person should be expected to handle.
As far as developing overlooked potential, the only real training opportunities arise when skilled positions open up. Anyone can qualify as an equipment operator whenever the training class is offered, but training for the higher-paying clerical jobs only occurs after candidates have been awarded the positions.
