An advocate is a specially trained customer service representative. In a client advocacy position, your responsibilities involve working directly with the clients of a company and representing their voice during internal decision making. Your everyday duties may vary based on the industry, but they typically include fielding calls from customers or meeting individual clients onsite, assessing their needs, and attending meetings with management to ensure that their offered services match the client’s interests. The title “advocate” can also refer to a role in the legal system, fighting for clients or a cause in court, but it most often refers to the customer support position.
