They always have exceptions. I had a friend who worked for a short time at a CDW warehouse where you are not allowed to bring in your phone. His son was just diagnosed with Type 1 Diabetes and needed to be able to contact him immediately if needed. Just required HR and some high up's approval and he could keep his phone on him (while silent). He was only allowed to take it out to answer his phone if his son called him.

CDW is a private company. Government would never grant an exception for this.
