Silent Employment Relationships: When No Contract Still Means Full Liability in Mexico
Why Employment Can Exist Without a Contract
In Mexico, an employment relationship does not require a written contract to be legally valid. Labor law recognizes employment based on facts, not paperwork.
When a person performs personal services under subordination in exchange for payment, courts assume full employment rights — even if no agreement was ever signed.
This is known as a silent employment relationship, and it creates complete employer liability.
The Legal Principle Behind Silent Employment
Mexican labor law establishes that:
- Employment exists once services are rendered
- Subordination is the decisive element
- Written contracts are evidence, not requirements
If a dispute arises, the absence of a contract typically benefits the worker, not the employer.
How Courts Identify Silent Employment Relationships
Subordination Without Paperwork
Courts examine whether the individual:
- Received instructions
- Followed company schedules
- Reported to a manager
- Was integrated into operations
Even informal or verbal instructions may establish subordination.
Payment as Proof of Employment
Any form of payment — including:
- Bank transfers
- Cash
- Foreign payments
can be treated as salary if linked to ongoing work.

Duration and Continuity
Ongoing services over time strongly suggest employment, even if originally intended as temporary or project-based.
Why “No Contract” Increases Employer Risk
When no written contract exists:
- Courts presume the worker’s version of events
- The burden of proof shifts to the employer
- Standard labor benefits are assumed
This often leads to higher liability than poorly drafted contracts.
Common Situations That Create Silent Employment
Informal Hiring During Growth Phases
Startups and scaling companies often hire quickly without formal HR processes.
Foreign Companies Testing the Market
Hiring “temporarily” without local registration creates silent employment.

Family or Referral-Based Hiring
Personal trust does not replace legal structure.
What Liability Employers Face
Silent employment triggers full labor obligations, including:
- Retroactive salary recognition
- Mandatory benefits
- Social security contributions
- Severance pay
- Overtime and holiday premiums
These obligations apply even if the employer was unaware.
Why Courts Favor Workers in Silent Employment Cases
Mexican labor law is protective by design. In ambiguous situations, courts prioritize worker protection.
The absence of formal documentation usually strengthens the worker’s claim.
Evidence Courts Commonly Accept
Courts rely on:
- Emails and messages
- Access badges or system logins
- Witness testimony
- Payment records
- Internal communications
Even indirect evidence can establish employment.

How to Prevent Silent Employment Relationships
Formalize All Working Relationships
Every person performing services should have a defined legal status.
Limit Informal Control
Avoid assigning tasks or managing individuals without contracts in place.
Register Employees Properly
IMSS registration and payroll compliance reduce exposure.

Why Silent Employment Is Hard to Defend
Once a court confirms subordination, defenses based on:
- Intent
- Informality
- Temporary arrangements
generally fail.
Prevention is far more effective than litigation.
Conclusion
In Mexico, the absence of a contract does not prevent employment — it often creates greater liability.
Silent employment relationships expose companies to full labor obligations, retroactive payments, and legal disputes. Companies that structure relationships clearly from the start are best positioned to avoid costly consequences.
