Today in our PCM we were told we can no longer carry a cell phone on our person, must be locked in back of package car and only when punched out oon meal is it to be touched. 1.they told us we can't leave diad in back of pkg car on meal due to heat, why do I have to put my iPhone back there for the same reason. 2. If there was a family emergency I can't hear it back there, checking phone every time go in bulk head door is not productive. 3.i am a swing driver so I am on a different route and use my phone for maps. Not while vehicle is moving of course. 4.3 of the 4 calls yesterday were from management.
