In businesses or teams’ sports, we are all teammates. Or at least, we should act it as such. However, can we act as leader too? In both businesses and sports, roles are often clearly defined. Captain or manager/team leader ‘separate’ things and formally receive the request to act as such. That way, they are recognized as such by others. But we all have the opportunity to act as leader and to help our team. In businesses or in sports. We will all face situations where leadership (even punctual) will bring value to the team. We would do so by listening to others, supporting them, bringing ideas, in sum showing responsibility. This is our duty.
