You’re only as good as the people who work for you. A bad boss is any employee's worst nightmare. Whether they work at a Fortune 500 company or the local hardware store, employees want to work for someone who knows how to motivate people and encourage them to become even better. There is a clear difference between simply being a boss and being a leader. Maintaining traits of great bosses get and keep great employees. Bosses explain; leaders inspire; bosses criticize; leaders mentor, bosses are superficial; leaders are genuine. Traits of great bosses directly lessen the chances of losing valuable employees.
If you’re the boss, then technically you might not need to be an effective speaker. People sort of have to listen to you, right? Maybe. But if you know how to communicate like a leader, then you won’t have to rely on seniority (or, fear). You want a team that both understands what you need and enjoys hearing how you say it.
