Right to Self-Organization's Constitutional Basis

What is the basis of the right of workers to organize themselves?

Under the 1987 Constitution, it is mandated that “the State affirms labor as a primary social economic force. It shall protect the rights of workers and promote their welfare.”

Consequently, the State is required to “guarantee the rights of all workers to self-organization, collective bargaining and negotiations, and peaceful concerted activities, including the right to strike in accordance with law.”

Further, the Constitution declares that “the right of the people, including those employed in the public and private sectors, to form unions, associations, or societies for purposes not contrary to law, shall not be abridged.”
