The correct answer is A; Participate in collective bargaining with the owners.
Collective bargaining is a legally enforceable agreement for a specified period between the management of an organization and its employees who are represented by an independent trade union. The contract defines the conditions of employment like wages, working hours and conditions, overtime payments, holidays, vacations and other benefits. In case a union member does not pay their union dues then they are not able to participate in collective bargaining with the owners.
