The Law of the Asymmetric Contract
Labor law exists because the employment contract is structurally unequal: the worker needs the job more than the firm needs any single worker. So the law tilts the field — minimum floors no contract can dig beneath.
The employment relationship has four defining notes: work that is personal, voluntary, dependent (under the employer's organization and direction), and for others' account (ajenidad — the fruits and risks belong to the employer, the worker gets a wage). Tick all four and labor law applies, whatever label the parties chose — the courts look at facts, not titles (the false self-employed problem).
Sources, stacked: Workers' Statute (Estatuto de los Trabajadores) → collective agreements (convenios colectivos, negotiated by unions and employers, binding for the whole sector or firm) → the individual contract, which can only improve on what the layers above grant:
Key rule: Law ≤ convenio ≤ contract — each level may only improve on the one below, never worsen it.
Core floors:
- Working time: maximum 40 hours/week on annual average; overtime limited and compensated.
- Wage: at least the minimum interprofessional wage (SMI), or the convenio's higher rate.
- Rest: daily and weekly rest, 30 calendar days of annual vacation minimum.
Endings: resignation by the worker; dismissal by the employer — which must be justified. Dismissals are judged fair (proven disciplinary or objective cause), unfair (improcedente — cause unproven: reinstate or compensate), or void (discriminatory or rights-violating: mandatory reinstatement).
For a manager, labor law is the operating system under every hiring plan: headcount costs, overtime arithmetic, and the price of getting a dismissal wrong.
The four defining notes
| Note | Meaning |
|---|---|
| Personal | The worker performs the work themselves |
| Voluntary | Freely agreed |
| Dependent | Under the employer's organization and direction |
| For others' account | Fruits and risks belong to the employer |
Common pitfall: Believing the contract's label decides. Courts apply the four notes to the facts: a "freelance" rider with fixed schedule, app-assigned routes, and company-set prices is an employee — the false self-employed doctrine exists precisely for this.
