Only drivers and one clerk have my cell number. I don't use my cell for work. If they want to get nasty with me it will have to be through the diad. Take pictures of the messages as needed. Such as the new sup who texted me "be back by 7 and finish your lunch in bldg." I sent back text, "not your call when and where I take lunch, send someone out to get nda, or do you want me to return, drop off nda and go back out". New drivers don't let ups have you cell number, they will call you all the time and harass you over it as well. If you get caught answering the cell and you are not parked with the engine off you can be fired on tbe spot. Use the diad for all messages. If they want you to call find a business phone to call from. Or like me just respond use diad for messages.
