I have heard that drivers in some areas (CA for one) are somehow "locked out" of their DIADS during lunch break in order to prevent them from working off of the clock. How does that work if the driver is eating lunch and a customer approaches him asking for a package that is on the truck? Can the lockout be overridden, and can the DIAD still send and receive messages during this time? Or does it literally become a non-functional piece of plastic until the lunch break is over? While in no way am I advocating working off of the clock, it is quite common for me to be approached by customers needing their stuff while I am on lunch. I always take the DIAD into the restraunt with me, and if they do have a package I will simply walk out to the truck and get it for them and then add an extra minute or two onto the end of my lunch so I'm not working for free. Same thing goes with answering messages from the office. I cant imagine how ashamed and embarassed I would be if a customer approached me needing an urgent package and I had to tell them to just stand there and wait for 37 more minutes until my lunch break was over.
