who are the parties to a listing agreement
Listing contract A listing contract (or listing agreement) is a contract between a real estate broker and an owner of real property granting the broker the authority to act as the owner's agent in the sale of the property.[1]
Closed shop A pre-entry closed shop (or simply closed shop) is a form of union security agreement under which the employer agrees to hire union members only, and employees must remain members of the union at all times in order to remain employed. This is different from a post-entry closed shop (US: union shop), which is an agreement requiring all employees to join the union if they are not already members.[1] In a union shop, the union must accept as a member any person hired by the employer.[2]
