Mexico’s May 2019 labour law reform has opened the door to a new era in labour relations. To encourage greater understanding and respect for the reformed labour law, the Mexico Committee of the Americas Group has prepared an Employer Guidance tool on Freedom of Association and Collective Bargaining; a summary of employer and union obligations under the Protocol for Authentication of Collective Bargaining Agreements; and a summary of the most significant rights and obligations regarding freedom of association and collective bargaining under Mexican labour law and International conventions.
