Union Leave Application Mexico (Solicitud de Licencia Sindical)

A Union Leave Application Mexico (Solicitud de Licencia Sindical) is a formal written request submitted by a union official, representative, or delegate (dirigente o representante sindical) to their employer seeking paid or unpaid leave from their regular duties to perform union-related activities (actividades sindicales). The document is grounded in Article 132, Fracción X of the Ley Federal del Trabajo (LFT), which obligates employers to permit workers who are union representatives or officials to perform union functions during working hours, and in the broader framework of freedom of association (libertad sindical) protected by Article 123, Apartado A, Fracción XVI of the Constitución Política de los Estados Unidos Mexicanos of 5 February 1917.

The constitutional guarantee of freedom of association under Article 123, Apartado A, Fracción XVI of the Constitución entitles both workers and employers to form and join organizations for the defense of their respective interests. The Ley Federal del Trabajo implements this guarantee through Articles 356 through 430, which govern the formation, registration, and functioning of unions (sindicatos), federations (federaciones), and confederations (confederaciones) in Mexico's private sector. The international dimension of this right is reinforced by Convention No. 87 of the International Labour Organization (OIT — Organización Internacional del Trabajo) on Freedom of Association and Protection of the Right to Organise (1948) and Convention No. 98 on the Right to Organise and Collective Bargaining (1949), both ratified by Mexico and incorporated into domestic law through Article 133 of the Constitución.

Article 132, Fracción X LFT imposes on employers the specific obligation to permit workers who hold positions in the union executive committee (comité ejecutivo del sindicato) or who have been designated as union delegates (delegados sindicales) or representatives (representantes) to perform their union functions during the working day, without deducting the time spent from their wages or seniority. The extent of this obligation — whether the employer pays the worker during the union leave, the maximum number of hours or days per period, and the activities covered — is typically regulated by the applicable collective bargaining agreement (contrato colectivo de trabajo — CCT) registered with the Centro Federal de Conciliación y Registro Laboral (CFCRL) under the post-2019 reforma laboral framework.

The 2019 reforma laboral (Decreto published in the Diario Oficial de la Federación on 1 May 2019) significantly strengthened union democracy and transparency obligations in Mexico. The CFCRL now administers a public registry of all unions and their collective bargaining agreements, and requires unions to conduct democratic elections for their leadership through secret ballot (voto personal, libre, directo y secreto) under the reformed Article 371 LFT. These reforms have increased the visibility and accountability of union representatives in their dealings with employers, making properly documented union leave applications an important component of the employer-union relationship.

The Secretaría del Trabajo y Previsión Social (STPS) has recognized union leave (licencia sindical) as a protected activity under the broader anti-discrimination framework of Article 3 LFT and the Ley Federal para Prevenir y Eliminar la Discriminación (LFPED) — employers may not retaliate against workers for exercising union rights or performing union functions, and denial of union leave without legitimate justification may constitute an unfair labour practice (práctica desleal) under Articles 387 and 388 LFT, subject to complaints before the Tribunales Laborales and the CFCRL.

A Union Leave Application Mexico is needed whenever a worker who holds a recognized union position — whether as a member of the union's comité ejecutivo (executive committee), as a delegado sindical (shop steward or delegate), as a union representative (representante sindical) in a specific department or shift, or as a member of a union commission (comisión sindical, comisión mixta, or comisión de seguridad e higiene) — requests time away from their assigned job duties to perform union-related activities during the employer's working hours.

The application is needed when a union official must attend collective bargaining negotiations (negociaciones del contrato colectivo de trabajo) with the employer's management. Under Articles 387 and 388 LFT, both parties to a CCT are obligated to participate in good faith in the collective bargaining process — employers must allow union negotiators sufficient time away from their regular duties to participate in these sessions, and the Solicitud de Licencia Sindical is the mechanism for formally requesting and documenting that time.

The document is required when a union representative must attend hearings, sessions, or meetings at the Centro Federal de Conciliación y Registro Laboral (CFCRL) — including union registration proceedings under Articles 365–370 LFT, CCT renewal and revision proceedings, individual conciliation hearings in which the union appears as the worker's representative, and the annual CCT audit and transparency reporting obligations created by the 2019 reforma laboral. CFCRL proceedings require the physical or electronic presence of designated union representatives, and the employer's obligation under Article 132, Fracción X LFT extends to CFCRL appearances.

A Solicitud de Licencia Sindical is needed when union leadership must conduct internal union business — convening assembly meetings (asambleas sindicales under Article 371, Fracción IV LFT), conducting democratic leadership elections under the reformed Article 371 LFT, reviewing and approving union financial accounts (estados financieros del sindicato), adopting positions on employer policies affecting union members, or consulting with the union's legal advisor (asesor jurídico sindical) about pending labour matters. The employer's obligation to permit these activities derives from the general principle of union autonomy under Articles 356–377 LFT and the OIT Conventions ratified by Mexico.

The application is also needed when union representatives participate in bipartite or tripartite bodies required by the LFT — including the Comisión Mixta de Capacitación y Adiestramiento (joint training commission under Article 153-F LFT), the Comisión Mixta de Participación de Utilidades (PTU joint commission under Article 125 LFT), the Comisión de Seguridad e Higiene (occupational safety and health joint committee under Articles 509–512 LFT), and the Comisión Mixta de Escalafón (seniority and promotion joint commission under Article 158 LFT). Participation in these statutory bipartite bodies is a worker right and employer obligation, and the Solicitud de Licencia Sindical documents the request to attend their sessions.

Under the NOM-035-STPS-2018 (psychosocial risk factors in the workplace), employers with 50 or more workers must establish policies for the promotion of workplace wellbeing that include consultation with worker representatives — a function that union representatives perform during licencia sindical time. Denial of union leave for participation in NOM-035 compliance activities constitutes both a labour law violation and an occupational safety non-compliance finding.

A valid Union Leave Application Mexico under Article 132, Fracción X of the Ley Federal del Trabajo must contain the following essential elements to obtain the employer's authorization and create an enforceable record of the union leave request.

Worker and Union Position Identification: Full legal name of the requesting worker (solicitante), RFC (Registro Federal de Contribuyentes assigned by the SAT), CURP (Clave Única de Registro de Población issued by RENAPO), NSS (Número de Seguridad Social assigned by IMSS), regular job position (puesto habitual), department (departamento o área), and the specific union position held (cargo sindical) — for example: Secretario General, Secretario de Trabajo y Conflictos, Tesorero, Vocal, Delegado Sindical, or member of a specific comisión mixta. The union position must be one that is recognized in the union's estatutos sindicales (union bylaws) registered with the CFCRL and in the applicable CCT.

Union Identification: Full name of the union (denominación o razón social del sindicato), CFCRL registration number (número de registro sindical en el CFCRL), and the sector or industry in which the union operates. Since the 2019 reforma laboral, all unions must be registered with the CFCRL, which maintains a public registry of all unions and their CCTs. Union registration numbers should be verifiable on the CFCRL public registry portal (cfcrl.gob.mx). Unions that were previously registered with the former Secretaría del Trabajo y Previsión Social (STPS) registry or with state Juntas de Conciliación y Arbitraje must have re-registered with the CFCRL under the transition provisions of the reforma laboral.

Employer Identification: Full legal name or business name (razón social) of the employer (patrón), RFC, Registro Patronal IMSS, and the name and title of the HR manager or director (gerente o director de Recursos Humanos) to whom the application is addressed. The application should reference the applicable CCT by its CFCRL registration number and revision date, since the CCT typically governs the specific conditions (duration, compensation, advance notice requirements) for union leave.

Activity Description: A clear and specific description of the union activity for which leave is requested — for example: attending CFCRL hearing scheduled for [date and time at specific CFCRL office]; attending CCT revision negotiation session with employer management; conducting union assembly at [location] to vote on [specific matter]; participating in Comisión Mixta de PTU session to review employer's annual ISR declaration; representing a union member in CFCRL mandatory conciliation hearing; or attending OIT regional conference as union delegate. The description must be specific enough for the employer to verify the legitimacy of the request — generic descriptions like "union business" are insufficient and the employer may legitimately request additional details.

Requested Leave Period: Specific start date and time (fecha y hora de inicio) and end date and time (fecha y hora de término) of the requested leave period, or, for recurring leave (licencia periódica), the schedule of recurring sessions (for example, every Tuesday morning from 09:00 to 13:00 for the duration of CCT revision negotiations). Advance notice requirements — typically 24 to 72 hours under applicable CCTs — must be respected. Emergency union leave (licencia sindical de urgencia) for unexpected events such as a sudden wildcat strike or emergency assembly may be requested with shorter notice, but this should be acknowledged in the request.

Compensation During Leave: Explicit statement of whether the leave is requested as paid union leave (licencia sindical con goce de sueldo) under the applicable CCT provision, or unpaid leave (licencia sindical sin goce de sueldo). The CCT registered with the CFCRL typically specifies the number of paid union leave hours per week or month that the employer must grant to recognized union representatives — common arrangements in Mexican CCTs include 8 to 40 hours of paid union leave per week for the Secretario General and 4 to 20 hours for other executive committee members. If the requested leave exceeds the CCT-guaranteed paid hours, the excess may be unpaid or may require a separate negotiation. The employer cannot deny leave that is within the CCT-guaranteed entitlement.

Seniority and Benefits Continuity: Confirmation that the worker's seniority (antigüedad), IMSS registration, INFONAVIT contributions, vacation entitlement under Article 76 LFT, aguinaldo rights under Article 87 LFT, and all other employment benefits continue to accrue during the authorized union leave period, consistent with Article 132, Fracción X LFT and the applicable CCT provisions. Interruption of seniority accrual during authorized union leave would constitute an unfair labour practice under Article 388 LFT.
