There are decisions that seem simple, but that affect salary, rights, and professional future. When a worker decides to terminate their contract, what they do before and at the time of leaving can determine whether they receive everything they are owed or end up paying for procedural errors.

Employee termination of a contract can occur in two main ways: voluntarily, with prior notice, or for just cause, when the employer's conduct makes it impossible to continue. Each path has different timelines, effects, and rights.

This article explains how contract termination works for employees, what they can claim in each scenario, and how to protect evidence and amounts to be received.

Termination, denunciation, and resolution: three words, three different effects.

In everyday speech, people say "I'm going to terminate the contract." In law, it's important to separate the concepts, because each has consequences.

When a worker terminates a contract on their own initiative, they may be giving notice of termination (leaving voluntarily) or terminating the contract (leaving for just cause, usually due to the employer's fault). The difference is not merely theoretical.

In a termination, as a general rule, there is prior notice and no compensation to be received, but there are final accounts.

In a termination for just cause, there may be no prior notice, and there may be right to compensation, if the basis fits the situations foreseen by law and is well communicated.

When can an employee terminate a contract with just cause?

Just cause is not simply "being fed up." It's a serious situation where the employer's behavior makes maintaining the contract unreasonable.

In practice, there are typical examples, often mentioned by the public services themselves, such as:

• culpable failure to pay compensation on time;
• negligent violation of workers' legal rights;
• application of an abusive sanction;
• culpable lack of safety, hygiene and health conditions at work;
• negligent injury to serious financial interests of the worker;
• Offenses against physical or moral integrity, honor, or dignity committed by the employer or their representative.

The key takeaway is this: just cause is always a "specific case." The court looks at facts, dates, evidence, and impact. And the worker has deadlines to act.

As a rule, the notice of termination must be given within 30 days of becoming aware of the facts, and must state the specific reasons.

If your situation involves harassment, it's advisable to address the issue with rigorous evidence gathering, because this is one of the areas where employers tend to deny everything. See also Workplace harassment.

Termination by mutual consent: what the law requires and what changes in practice.

When an employee leaves voluntarily (by resigning), the rule is simple: the company does not have to accept the resignation, but the employee must give prior notice and communicate this in writing.

The most frequently cited deadlines in practice are:

• 30 days' notice if you have up to 2 years of seniority;
• 60 days' notice if you have been employed for more than 2 years.

This framework is widely referenced in guidebooks and corresponds to the general logic of Labor Code for the worker to file a complaint.

In fixed-term contracts, the deadlines can vary, making it even more important to confirm the type of contract you have. To better understand what you have signed, see [link/reference]. Types of employment contracts.

Advance warning: the detail that costs the most when ignored.

Many people hand in the letter and think "it's done." But there's a sensitive point: if you don't fulfill the notice period, you may have to pay the company compensation corresponding to the missing period.

This happens because the law protects the employer from the damage caused by an immediate departure without time for a replacement.

In practice, the amount tends to be calculated based on the compensation corresponding to the days that were not worked.

There are exceptions and nuances, especially when there is just cause, and therefore it is dangerous to make hasty decisions without assessing whether you are in a situation of complaint or resolution.

Termination with just cause: how to do it without failing in form.

When dismissal is for just cause, what often goes wrong is not the reason. It's the manner in which it's handled.

To reduce risk, the communication should be prepared as if it were a piece of evidence.

What should normally be included:

• Employee and company identification;
• date;
• An indication that you are terminating the contract with just cause.;
• An objective description of the facts, including dates, locations, and examples;
• reference to the fact that the continuation of the contract has become unenforceable;
• indication of the effect (immediate, or as soon as possible when continuity is incompatible);
• Request for final settlements and, where applicable, request for compensation.

In addition to communicating, it's advisable to keep proof of sending and receiving. As a rule, registered mail with return receipt requested is the most secure method. In-person delivery with a signed receipt is also acceptable.

If your case involves unpaid wages, publicly available information indicates that there are situations where the timeframe and method of communication have specific requirements, including references to periods of 60 days of non-payment before the deadline begins to run in certain scenarios.

Am I entitled to compensation if I terminate my contract?

This is the question that decides almost everything.

If the employee leaves voluntarily, as a general rule they are not entitled to severance pay or termination benefits. They are, however, entitled to a final settlement.

If an employee terminates their contract with just cause due to culpable conduct on the part of the employer, they may be entitled to compensation, the calculation of which is often described as between 15 and 45 days of base salary and seniority allowances for each full year of service, with a minimum of 3 months.

The specific amount depends on the severity of the situation and the context of the case.

When serious harm, harassment, repeated breaches of contract, or serious violations of guarantees are at stake, the way in which it is proven and framed makes all the difference.

What are you always entitled to receive when your contract ends?

Even when there is no right to compensation for termination, some rights do not disappear.

Specifically, upon termination of the contract, the employee is normally entitled to final settlements, which include accrued and prorated amounts, such as wages due, accrued and unused vacation days, vacation pay, and prorated Christmas bonus, depending on the situation.

Payment for unused vacation time is one of the most frequent items in the final settlement, and there are rules and deadlines for claiming it. If this is your issue, see [link/resource]. Unused vacation time: can I demand payment?.

Unemployment benefits: the mistake that leads to hasty decisions.

Many people make the decision to terminate their employment without checking the impact on their unemployment benefits.

The rule of thumb is simple: when leaving a job is voluntary, there is usually no access to unemployment benefits, because there is no situation of involuntary unemployment.

In some cases, when there is a termination with just cause (and the classification is recognized), the situation may be different.

Since this topic depends on requirements and proof, it is worth approaching it with caution and, if necessary, articulating the strategy with solid documentation.

When is it worthwhile to speak to ACT first, and when does it make sense to take things further?

There are situations where the first step is not to "deliver the letter".

For example, when there is a breach of safety conditions, non-payment, abusive working hours, or harassment, it may make sense to gather evidence and, in certain cases, involve the ACT (Authority for Working Conditions).

But be aware: administrative intervention does not replace the protection of your case, nor does it guarantee compensation.

The choice between attempting to resolve the issue, reporting it, or pursuing a resolution with just cause should be made strategically.

The risk of a parallel disciplinary process.

In tense environments, a pattern emerges.

The worker begins to demand their rights, and the company reacts with disciplinary action, sometimes with a formal notice of charges, attempting to create grounds for dismissal.

If this is happening to you, don't treat it as "just another letter." The response, the deadlines, and the proof matter.

A practical guide to terminating a contract without harming yourself.

Before moving forward, it helps to have a simple plan, designed to reduce risk.

• Confirm the type of contract and its length of service.
• To determine if the departure is due to a complaint or if there are genuine grounds for just cause.
• Gather evidence: messages, emails, receipts, schedules, witnesses, medical reports when applicable.
• Confirm deadlines: advance notice upon termination, 30 days to communicate in many just cause scenarios.
• Prepare the letter with facts, dates, and objective language.
• Send via email with proof of delivery.
• Clearly request final adjustments.

This guide seems simple, but it avoids most of the mistakes that later lead to litigation.

Common mistakes that cost money and years.

There are patterns that repeat.

• Leaving "in the heat of the moment" without realizing whether it's a complaint or just cause.
• Failing to give prior notice and being surprised by a compensation claim from the company.
• Invoking just cause with vague phrases, lacking facts and dates.
• Do not keep proof of sending and receiving the communication.
• Do not request the final accounts in writing and let deadlines pass.
• Forget about unused and proportional vacation time.

Conclusion

Terminating a contract from the employee's perspective doesn't have to be a leap in the dark. It can be a clean step, with protected rights and controlled risk, as long as the decision is made methodically.

The key question is always the same: are you leaving voluntarily, with prior notice, or are you terminating the contract for just cause, with facts that make it impossible to continue? From there, everything changes: deadlines, letter, proof, compensation, and even the impact on benefits.
