I just brought in a new-to-my-team employee 1.5 weeks ago. (He's been with the company about a year.) I know it's only been short time but he's already displaying some disturbing behaviors: playing on his phone, disappearing from his desk for 45 minutes at a time, sleeping in my staff meeting, lack of motivation/engagement in picking up new tasks. Obviously, I'm not at the negative feedback phase of the trinity. If I wait to build a relationship before addressing the problem behaviors will I have created an environment of acceptance for these issues? I really want to set some ground rules for him. Any advice?
