This is exactly what's wrong with our neiep education program guys. How is it possible this service tech is unaware of how a dmm works? ! The program is outdated and doesn't cover 25% if what it should imo. Where is the company training? We have some serious problems coming in the near future since half of our union workforce will be retiring in less than 10 yrs. It's hard to argue that we deserve raises and more bennies when our bros are lacking the knowledge to do their jobs. We all have to step up and teach the upcoming generation and re-vamp the neiep program to include more technical skills of troubleshooting electronics. Cmw007, Google it bud.
