People tend to resent other people telling them how to do their jobs. A team dynamic requires trust between teammates and nothing robs trust like being told how to do something. Most people understand that leaders must empower others by not micromanaging them. What doesn’t always get talked about is when a peer micromanages you. Constant disapproving statements and unsolicited advice are toxic to any team dynamic. Resist the “know-it-all” by confronting them with the simple question of “Do you trust me?” Let them know that you welcome input but that the final call rests with you.
