Professionalism is the way an individual conducts themselves at work. Your attitude, words, and actions together present a picture of you. And if you think no one will notice whether you act professionally or not, think again. No matter what your job is—from waitress to lawyer and everything between—professionalism is a sign of an employee who cares. Your customers, clients, boss, and coworkers will recognize you as knowledgeable and hardworking. It also shows that you respect others and are responsible.
