Specific Work or Task Employment Contract Colombia (Contrato de Obra o Labor Determinada)

A Specific Work or Task Employment Contract Colombia (Contrato de Obra o Labor Determinada) is a formal employment agreement between an empleador (employer) and a trabajador (worker) in which the duration of the contract is tied to the completion of a specific work, project, or task, governed by Article 45 literal d of the Código Sustantivo del Trabajo (CST) — Decreto Ley 2663 de 1950. Under this modality, the employment relationship begins when the worker commences the assigned work and terminates automatically upon the completion of the defined obra or labor, without the need for advance notice or indemnification.

Article 45 of the CST establishes four modalities of employment contract duration: indefinite term, fixed term, duration of a specific work or task (obra o labor determinada), and occasional or transitory work. The obra o labor contract occupies a distinct legal position because its termination does not depend on a calendar date or the will of the parties but rather on an objective, verifiable event — the completion of the assigned work. The Sala de Casación Laboral of the Corte Suprema de Justicia has consistently held that the specific work must be clearly defined and objectively determinable at the time of contracting; vague descriptions such as "for the duration of the project" without further specification have been deemed insufficient.

The constitutional basis for this contract modality rests in Articles 25 and 53 of the Constitución Política de 1991. Article 25 declares work a fundamental right and social obligation deserving special State protection. Article 53 mandates minimum labour guarantees including employment stability, the principle of most favourable condition (condición más beneficiosa), and the primacy of reality over formal agreements (primacía de la realidad). The Corte Constitucional, in Sentencia C-016 de 1998, affirmed that obra o labor contracts are constitutionally valid when the specific work is genuinely defined and not used to circumvent employment stability protections.

Every obra o labor contract triggers mandatory affiliation to the Sistema General de Seguridad Social Integral under Ley 100 de 1993. The employer must register the worker through the Planilla Integrada de Liquidación de Aportes (PILA) before the first day of work. Registration includes health insurance through an Entidad Promotora de Salud (EPS) — employer 8.5%, worker 4% — pension contributions through Colpensiones under the Régimen de Prima Media (RPM) or a private Administradora de Fondos de Pensiones (AFP) under the Régimen de Ahorro Individual con Solidaridad (RAIS) — employer 12%, worker 4% — and occupational risk insurance through an Administradora de Riesgos Laborales (ARL) funded entirely by the employer at rates between 0.348% and 8.7% depending on the risk classification under Decreto 1295 de 1994 y Ley 1562 de 2012.

All prestaciones sociales apply proportionally to obra o labor contracts. Cesantías equal one month's salary per year of service, deposited proportionally in the worker's Fondo de Cesantías under Ley 50 de 1990 Article 14. Intereses sobre cesantías at 12% annual are paid under CST Article 249. The prima de servicios under CST Article 306 is calculated proportionally. Vacaciones accrue at 15 business days per year under CST Article 186. Dotación under CST Article 230 applies to workers earning up to two SMLMV who complete at least three months of service.

The Ministerio del Trabajo (MinTrabajo) oversees enforcement of obra o labor contract regulations through workplace inspections under CST Articles 485 through 487. The Decreto Único Reglamentario del Sector Trabajo — Decreto 1072 de 2015 — consolidates regulatory provisions governing employment relationships. Employers must implement a Sistema de Gestión de Seguridad y Salud en el Trabajo (SG-SST) per Resolución 0312 de 2019. The SMLMV for 2025 is COP$1.423.500 per Decreto 2292 de 2024, with an auxilio de transporte of COP$200.000 for workers earning up to two SMLMV.

The Unidad de Gestión Pensional y Parafiscales (UGPP) actively audits obra o labor arrangements to verify that employers correctly calculate and report parafiscal contributions — 4% to Cajas de Compensación Familiar (CCF), 3% to Instituto Colombiano de Bienestar Familiar (ICBF), and 2% to SENA — through the PILA system. Under Ley 1607 de 2012 Article 25, employers are exempt from SENA and ICBF contributions for workers earning less than ten SMLMV.

Colombian labour courts — Juzgados Laborales del Circuito — adjudicate disputes arising from obra o labor contracts, with appeals to the Sala Laboral of the Tribunal Superior de Distrito Judicial and cassation review by the Corte Suprema de Justicia.

A Specific Work or Task Employment Contract Colombia is required whenever a Colombian employer needs to hire a worker for a defined project, task, or assignment whose completion marks the natural end of the employment relationship. Article 45 literal d of the Código Sustantivo del Trabajo authorizes this contract modality when the duration of work is determined by the nature of the obra o labor contracted, rather than by a calendar date or the indefinite continuation of services.

Construction companies registered with the Cámara de Comercio use obra o labor contracts extensively when hiring workers for specific building projects — from foundation to handover — under the occupational health and safety standards of Decreto 1072 de 2015 and the construction-sector risk classifications of Decreto 1295 de 1994. The contract naturally terminates when the construction milestone or phase is completed, as verified by the acta de recibo de obra.

Agricultural enterprises governed by the DIAN as persona natural comerciante or as Sociedad por Acciones Simplificada (SAS) under Ley 1258 de 2008 use obra o labor contracts for harvest-specific hiring — coffee, sugarcane, palm oil, and flower production cycles that have objectively determinable endpoints. The Ministerio del Trabajo has recognized these seasonal agricultural activities as legitimate grounds for obra o labor contracting.

Technology companies and consulting firms use this modality when engaging software developers, data analysts, or specialized engineers for defined project deliverables — a mobile application, a data migration, or an infrastructure deployment — where the scope of work has measurable completion criteria. The contract must specify the deliverables and acceptance criteria with sufficient precision to satisfy the specificity requirement established by the Sala de Casación Laboral of the Corte Suprema de Justicia.

The obra o labor contract is also needed when an employer hires a replacement worker for the duration of a specific absence — such as a maternity leave under CST Article 236 as modified by Ley 1822 de 2017 — where the replacement period is tied to the return of the absent worker rather than a fixed calendar date.

Under the principio de primacía de la realidad (CST Article 23, Constitución Política Article 53), Colombian labour courts will reclassify an obra o labor contract as indefinite when the defined work is vague, the worker continues performing identical functions after the supposed completion of the obra, or the employer repeatedly assigns new projects without executing separate contracts. The Corte Constitucional in Sentencia T-449 de 2010 reinforced that indefinite re-engagement under successive obra o labor contracts for the same functions constitutes evidence of a permanent employment relationship.

The document is needed for social security registration under Ley 100 de 1993 and Decreto 1406 de 1999, as the employer must register each worker in the PILA system with affiliation to EPS, AFP or Colpensiones, and ARL before the first day of work. The written obra o labor contract specifying the defined work, salary, and completion criteria serves as the foundational document for calculating proportional prestaciones sociales and parafiscal contributions — 4% to CCF, 3% to ICBF, and 2% to SENA — reported through the PILA system under Ley 1607 de 2012.

A valid Specific Work or Task Employment Contract Colombia under Código Sustantivo del Trabajo Article 45 literal d must contain the following elements to be enforceable and to meet social security registration requirements under Ley 100 de 1993 and Decreto 1072 de 2015.

Identification of Parties: Full legal name, cédula de ciudadanía (for Colombian nationals) or cédula de extranjería (for foreign residents), and domicile of both the employer and employee. Where the employer is a persona jurídica, the company's NIT (Número de Identificación Tributaria assigned by the DIAN), Cámara de Comercio matrícula mercantil number, and identification of the representante legal must be included, verified through a Certificado de Existencia y Representación Legal.

Specific Work Description (Obra o Labor): The most critical element of this contract modality. The obra or labor must be described with sufficient precision to identify exactly what work will be performed, its scope, and the objective criteria that will determine its completion. The Sala de Casación Laboral of the Corte Suprema de Justicia has invalidated contracts where the work description was vague or open-ended, reclassifying them as indefinite contracts under CST Article 45. Acceptable descriptions include: construction of a specific building phase, development of a defined software application, completion of an audit for a specified fiscal year, or harvesting of a particular crop cycle.

Completion Criteria: Clear, objectively verifiable criteria for determining when the obra or labor has been completed. For construction projects, this may reference the acta de recibo de obra; for technology projects, the acceptance of defined deliverables; for agricultural work, the completion of the harvest season. The completion event must be determinable by both parties without ambiguity.

Job Position and Functions: The specific job title (cargo) and description of functions the worker will perform in connection with the defined obra or labor. The work location must be specified, along with the modality — presencial, teletrabajo under Ley 1221 de 2008, or trabajo en casa under Ley 2088 de 2021.

Salary and Payment Terms: The agreed monthly salary in Colombian Pesos (COP), which must meet or exceed the SMLMV — COP$1.423.500 for 2025 per Decreto 2292 de 2024. Workers earning up to two SMLMV receive the auxilio de transporte (COP$200.000 monthly). Payment frequency per CST Article 134.

Trial Period: Under CST Articles 76 and 77, the trial period for obra o labor contracts must be expressly stipulated in writing and may not exceed two months. During the trial period, either party may terminate without notice or indemnification.

Mandatory Benefits (Prestaciones Sociales): Proportional cesantías under Ley 50 de 1990 Article 14; intereses sobre cesantías at 12% under CST Article 249; proportional prima de servicios under CST Article 306; proportional vacaciones under CST Article 186; dotación under CST Article 230 for qualifying workers; and social security through EPS, AFP/Colpensiones, and ARL under Ley 100 de 1993.

Automatic Termination: Statement that the contract terminates automatically upon completion of the defined obra or labor under CST Article 61 numeral 1 literal d, without the need for advance notice or indemnification. Reference to CST Article 64 for indemnification in cases of unjustified early termination by the employer before the obra is completed — which requires payment of damages equivalent to the salary the worker would have earned for the reasonably remaining duration.

Occupational Health and Safety: Reference to the employer's obligation to implement a Sistema de Gestión de Seguridad y Salud en el Trabajo (SG-SST) under Decreto 1072 de 2015, Título 4, Parte 2, Libro 2, and Resolución 0312 de 2019. Workers on obra o labor contracts in high-risk sectors (construction, mining, agriculture) must receive specific safety training and personal protective equipment.

Data Protection: Under Ley 1581 de 2012 and Decreto 1377 de 2013, the employer must inform the worker of personal data processing, with the Superintendencia de Industria y Comercio (SIC) as the enforcement authority.

Governing Law: The contract is governed by the CST, Ley 100 de 1993, and Decreto 1072 de 2015. Labour disputes are submitted to the Juzgado Laboral del Circuito, with pre-litigation conciliation under Ley 640 de 2001.

Parafiscal Contributions: The employer must calculate and remit parafiscal contributions for obra o labor workers — 4% to Cajas de Compensación Familiar (CCF), 3% to Instituto Colombiano de Bienestar Familiar (ICBF), and 2% to SENA — through the PILA system. Under Ley 1607 de 2012 Article 25, employers are exempt from SENA and ICBF contributions for workers earning less than ten SMLMV, provided all other social security obligations are current. The UGPP conducts audits to verify parafiscal compliance and may impose sanctions for underreporting or late payment.

Non-Competition and Confidentiality: Where the obra or labor involves access to proprietary information, trade secrets, or sensitive business data, the contract should include confidentiality obligations under CST Article 58 numeral 10 and reference the employer's data protection policy under Ley 1581 de 2012. Post-contractual non-competition clauses must be reasonable in scope, duration, and geographic coverage to be enforceable under Colombian jurisprudence.
