Marta needs an electrician to do some work at her home. Her father advises her to make sure that the firm she plans to hire is not a closed shop. Marta is not sure what this means, but later learns that the "closed shop" that her father was referring to is:
a. a place of employment in which most of the workers are union members.
b. a firm that requires union membership by its workers as a condition of employment.
c. a firm that keeps its doors closed to union members.
d. a firm that prohibits any efforts to introduce a union among its employees.

b. firm that requires union membership by its workers as a condition of employment

Explanation:

A closed shop also called a pre-entry closed shop refers to an agreement whereby the employer only hires an employee if he has union membership and must remain a member of that union to continue in employment. It is a form of security agreement to ensure genuiness of employee. Closed ship is opposed to post-entry closed shop or union shop which requires the employee to become a member of a union if they are not already members, and must be accepted by the union.
