What you have learned from your individual experiences is entirely different from your coworkers. Thus, teamwork also maximizes shared knowledge in the workplace and helps you learn new skills you can use for the rest of your career.
Collaborating on a project creates an enthusiasm for learning that solitary work usually lacks. Being able to share discoveries with the rest of your team excites employees and fosters both individual and team knowledge.
