How would one go about giving feedback to a direct report if they seem to be using their cell phone a lot during work hours? This employee also operated his own business that he took a reduced role in to work in my organization. I often see this employee looking at his phone laying flat on his desk, replying to messages and has his earbuds plugged into the phone and in ear. I feel that this employee is either handling their business related work or personal items while at work.
The difficulty is that there is no direct proof to show the employee and they can say they are not doing this.
