An office or post with no work but high pay

Here are brief explanations of each option:

• Honorary means “given or done without payment or expectation of payment.” Honorary positions are often given to people who have made significant contributions to a particular field or organization.
• Gratis means “free of charge.” Gratis work is often done by volunteers or interns who are looking to gain experience or make connections in their field.
• Ex officio means “by virtue of one’s office.” Ex officio positions are often given to people who hold certain other positions, such as the president of a company being a member of the board of directors.
