What is the role of a bargaining unit?

The labor organization designated or selected by the majority of the employees in an appropriate collective bargaining unit shall be the exclusive representative of the employees in such unit for the purpose of collective bargaining. However, an individual employee or group of employees shall have the right at any time to present grievances to their employer. Any provision of law to the contrary notwithstanding, workers shall have the right, subject to such rules and regulations as the Secretary of Labor and Employment may promulgate, to participate in policy and decision-making processes of the establishment where they are employed insofar as said processes will directly affect their rights, benefits and welfare. For this purpose, workers and employers may form labor-management councils: Provided, That the representatives of the workers in such labor-management councils shall be elected by at least the majority of all employees in said establishment. (As amended by Section 22, Republic Act No. 6715, March 21, 1989; Art. 267)
