This was an email from one the managers:
Just wanted to reiterate to everyone to stop shopping, texting, or looking at social media during work hours. There have been some of you that I have told on multiple occasions to get off your phone. We have plenty of work and your phones are a preventing some individuals to lose concentration on correctly processing your work. This is my final warning. Word of advise for all of you, talk to your co-worker/friends to stay off their phones, the next individual management “catches”, everyone’s phone will be off your desk.
