The document discusses grievance machinery and voluntary arbitration under Article 260 of the Labor Code. It defines grievance machinery as a committee created to appreciate complaints filed by dissatisfied employees through an orderly process established in collective bargaining agreements. The grievance process is designed to quickly resolve issues, eliminate misunderstandings, and improve employee morale. It also outlines principles the grievance machinery is expected to conform with, such as ensuring employees can discuss issues informally and receive a speedy and impartial resolution at the lowest possible level. Finally, it provides five points to prepare a formal grievance - listen to facts, test if it qualifies as a grievance, investigate further, write out details of the grievance, and present it.
