Before the action, the body blamed Park for violating the basic right of the union and suppressing its activities through the issuance of an illegal document, follow-up measure, secret cooperation between the public security forces and conservative organizations.

The cancellation of the official document that was issued under Park's rule would mean abolition of one evil, the organization said.

It declared they would start sit-in for the withdrawal of the document, revision of the law on trade union and acquisition of three rights to labor.
