What is profesional relationship at workplace?

A professional relationship is one in which people share things like ideas, tasks, and setting goals for the company for which they work. People with whom you have a working relationship are known as associates. Associates may be people working in the same company or a different company whose goals are similar. An example would be real estate brokers. One representing a buyer and one representing a seller. Their goal is the same, to get the house sold in a manner that is agreeable to both buyer and seller. They are working as professional associates in the real estate profession.

A professional relationship precludes (is without) any personal or romantic interests.
