I'm not supposed to love you, I'm not supposed to care. I'm not supposed to live my life wishing you were there. I'm not supposed to wonder where you are and what you do. I'm sorry, I can't help it, I'm so in love with you.
Thus the term team work originates from the concept of a team and in simple terms refers to doing work in a team or group. According to Business Directory, team work has been defined as the process by which a group of people work collaboratively to achieve a set or given goal/ task.
Teamwork takes cooperation up a notch because in this case, the individuals share a common goal. This is important in organizations that often operate in silos and require cross-functional actions to achieve a goal, e.g. putting on a company trade show. Teams form as needed and disperse when the goal is reached.
