Amy,We too have dealt with this as communication devices have become more sophisticated over the years. We have a "communication device" policy which indicates they are not allowed to have their communication device on their desk during work. (we were all inclusive in the naming as people were trying to get away with alternative words)We strictly enforce this, more for distractions than for concerns regarding breaches. Staff can request to have it on their desk if they are awaiting a critical personal call, but need to seek approval from their supervisor.That policy coupled with calling people out immediately and following up with discipline has made this a non-issue in our area and we have had the policy for 5+ years. We have "sneakers" from time to time, but the first time disciplined.... doesn't happen again.
Best of luck!
We too have a hospital policy limiting the use of personal communication devices, but unfortunately, not all management follows the policy. I do ask my staff to put it "away" when I see the phone
out on their desk - playing games or scrolling through. I know of an employee who states she is going to "the restroom" and is always gone for 15-20 min - not due to medical issue (at least not that I am aware of) LOL
They find a way to work around the policy.
