Confident employees have everything going for them. They are valuable assets for companies owing to their self-motivated and positive nature. They exhibit leadership qualities, aren’t afraid to take risks and tend to be extremely reliable. But what happens when that ‘confidence’ turns into arrogance? How do you deal with a cocky team member who gets onto everyone’s nerves because they are so full of themselves? Turning a blind eye over someone’s toxic attitude will not bring about any change. As the team leader, it is your responsibility to mentor that overconfident employee before their behavior affects your team’s productivity.
