Types of employment contract in Uruguay, explained simply

If you're about to hire someone — or you're about to be hired — it helps to know that in Uruguay not all contracts are the same. As a rule, an employment contract is open-ended (indefinido); the other forms (fixed-term, seasonal, trial, for-a-specific-work) are exceptions justified by the nature of the task. Here's each type in plain language, no jargon, and what happens when it ends.

The general rule: the open-ended contract

The open-ended contract (por tiempo indefinido, or simply indefinido) is the standard, presumed form: it has no agreed end date and lasts as long as the relationship does. In practice, if you hire someone for an ongoing task in your business, the natural form is open-ended. The other modalities aren't chosen 'just because': they need an objective reason tied to the work. Setting an end date, or labelling a role 'seasonal' when it's really permanent, can end up being treated as an open-ended contract anyway.

Fixed-term contract (a término / plazo fijo)

This is the contract with an end date or term agreed in advance. It fits when there's a concrete, temporary cause: covering a leave, a project of known duration, a bounded workload spike. The key is that the term answers a real need with a beginning and an end; it's not a way to dodge the worker's rights. While it lasts, the worker has the same benefits as anyone else (aguinaldo, leave, holiday pay) in the corresponding proportion.

Seasonal contract (zafral / de temporada)

The seasonal (zafral) contract is a particular case of fixed-term work: it's used when the activity is seasonal by nature — the harvest, the summer tourism season, a production peak — and it ends when the season does. It's very common in agriculture, construction and tourism. Like the fixed-term contract, it requires an objective cause: a genuine season with a start and a finish. It can't be used to disguise a role that is in fact year-round.

Trial contract (probationary period)

Many people believe there's a free 90-day 'trial period' during which you can dismiss at no cost. Careful: it's not quite like that. For a monthly worker, the Ministry of Labour states that no seniority is required to have the right to severance. Describing common-regime dismissal, it puts it like this:

MTSS, common-regime dismissal (monthly workers):

«Se aplica a todo trabajador de la industria, comercio, actividades privadas en general y servicios públicos a cargo de particulares; no se exige antigüedad»

In English: It applies to every worker in industry, commerce, private activities in general and public services run by private parties; no seniority is required

In plain terms: you can agree a trial stage and assess the person, but for a monthly worker there's no 90-day 'window' in which dismissal is free; labour protections run from the start. Other modalities and sectors have their own rules, so it's worth checking the specific case with the MTSS or a labour lawyer before assuming 'there's a trial'.

For-a-specific-work contract (por obra o servicio)

This one is tied to a specific work or service: it lasts as long as it takes to complete that particular task. When the work is finished, the contract ends. It's a variant of fixed-term work where the 'end' isn't a fixed date but the completion of the agreed task. Like the other forms, it must answer a concrete, bounded task, not a permanent need in disguise.

What happens when it ends: benefits and severance

Two important ideas. First: even if the contract is temporary, the work still generates benefits (aguinaldo, leave, holiday pay) in proportion to the time worked; they don't vanish because it's a short term. Second: severance depends on the contract type. The MTSS common regime itself specifies who has no right to the standard severance when the relationship ends as planned:

MTSS, common-regime dismissal:

«No tienen derecho a indemnización: los trabajadores zafrales; los contratados para tareas transitorias; los contratados a término.»

In English: The following are not entitled to severance: seasonal (zafral) workers; those hired for transitory tasks; those hired for a fixed term.

So: if a seasonal, transitory or fixed-term contract ends at its foreseen term or cause, under the common regime it generates no severance. But beware: cutting it short early, chaining temporary contracts, or using a modality for genuinely permanent tasks can make severance rights arise. These nuances are resolved case by case.

Before deciding which contract to use, it's worth confirming the detail: each branch's collective agreements, sectors with their own rules, and case law all change the picture. The Ministry of Labour offers free labour consultations, and for a specific case a labour lawyer is the safest route.

Frequently asked questions

• What's the 'default' contract? The open-ended one: no end date, it's the standard, presumed form.
• Can I set any end date? Only if there's an objective, temporary cause (cover, project, season). A term with no real cause can be treated as open-ended.
• Does a seasonal worker lose aguinaldo and leave? No: benefits accrue in proportion to the time worked.
• Is there a free 90-day trial period? For a monthly worker, the MTSS states no seniority is required for the right to severance; there's no free dismissal window.
• Does a fixed-term contract generate severance when it ends? If it ends at its foreseen term or cause, under the common regime no; cutting it short or chaining it can change that.
• Where do I check my case? At the MTSS (free consultations) or with a labour lawyer.

In short: in Uruguay the open-ended contract is the norm and the other forms — fixed-term, seasonal, trial, for-a-specific-work — are exceptions that need an objective reason. All of them generate proportional benefits, and severance on ending depends on the contract type and how it closes. When in doubt, confirm with the MTSS or a labour lawyer before signing.
