If the company planned to use PVD drivers during a work stoppage (strike or lockout) they would have to develop an app for them to use their own phone (which they have).
Most phones don't have the capability of capturing a signature so UPS would have to stop requiring a sig at businesses, and implement the policy in advance so shippers and receivers would be used to it by strike time...which they just did.
There would also have to be routing software in place with most of the bugs worked out ahead of time for clueless PVD drivers...Not as efficient as an experienced driver, but it would need a long break-in period (Orion).
Will the Teamsters now allow PVD drivers for the peak season, prior to the contract, so they are ready to roll next August?.
