A Secret No One Tells New Managers
"Controlled confrontation is a key part of being a boss... Your objective is for your team member to leave your meeting thinking about what will change and not how you treated them...
Start with the facts. Just the facts. Drain away the adjectives and describe the behavior or performance in neutral language. This should only take a few seconds.
Move right on to describing the impact of the performance or behavior that you want to change. Describe the impact in logical and emotional terms."
