Legal Character of Termination in Labor Disputes, Mediation as Condition of Action and Evidence Regime: Doctrinal and Jurisprudential Analysis

LEGAL NATURE OF TERMINATION IN LABOR CASES, MEDIATION AS A CONDITION FOR FILING SUIT, AND THE BURDEN OF PROOF: AN EXAMINATION BASED ON DOCTRINE AND CASE LAW

1. Introduction: Termination as the "Central Problem" of Labor Cases

A significant portion of disputes in labor law litigation is connected, directly or indirectly, to the fact of "termination." Many items such as severance pay and notice pay, reinstatement, pay for idle periods, union compensation, bad faith compensation, unused leave pay, and overtime receivables either become due with termination or become subject to an entirely different legal regime depending on the type of termination. For this reason, the first step in theoretically understanding labor cases is to correctly position the legal nature of the concept of "termination" and the consequences of the declaration of termination.

The generally accepted approach in doctrine considers that, due to the character of the employment contract that creates a continuous obligation relationship, the termination of the contract must be addressed through a different "protection" paradigm from classical contract law logic (performance–impossibility–invalidity of contract, etc.). Mandatory rules in favor of the employee, the job security system, and evidence regulations are parts of this paradigm. The established expressions of the Court of Cassation regarding the legal nature of termination also confirm this doctrinal line: termination is a right that produces results through a unilateral declaration of will and constitutes a disruptive right-creating declaration that must reach the other party.

In this article, the three axes that are most determinative in practice in labor cases will be examined together: (i) the legal nature and types of termination, (ii) the effect of mediation as a condition for filing suit on procedure and statute of limitations, (iii) the burden of proof and evidence strategy. The aim is not merely to summarize legislation but to build a "working bridge" between case law and doctrine that will directly contribute to the practitioner's file structure.

2. Termination Theory: Disruptive Right-Creating Right, Declaration That Must Reach the Recipient

2.1. Legal Nature of Termination

In Court of Cassation case law, termination is defined as a right that is "disruptive and right-creating" and "must be directed at the other party." This definition technically resolves many debates in labor cases. Because in disruptive right-creating rights, the legal consequence arises automatically when the declaration reaches the recipient; acceptance by the other party is not required.

Indeed, the 22nd Civil Chamber explicitly emphasizes the unilateral character of termination and its nature as a declaration that must reach the recipient: termination produces its consequences from the moment it reaches the other party and does not require acceptance by the addressee. The practical implication of this approach is: even if the employee says "I do not accept" (for example, while reserving the request for reinstatement), the contract is considered to have ended; however, if the termination is invalid, its legal consequences change (reinstatement, compensation, etc. come into play).

2.2. Termination with Notice – The Typical Regime for Indefinite-Term Contracts

The Court of Cassation views termination with notice as a typical institution for indefinite-term contracts. In the 7th Civil Chamber decision, it is stated that "termination with notice is applicable for indefinite-term employment contracts," indicating that the logic of "granting notice period" does not operate in the same way for fixed-term contracts. This distinction changes the calculation method for many items such as notice pay, remaining term pay, and the consequences of wrongful termination of the contract.

Doctrinally, the notice periods in indefinite-term contracts serve a dual "balancing" function: protecting the employee's opportunity to find new employment, and protecting the employer's work organization from sudden shocks. The Court of Cassation's finding that "notice periods are relatively mandatory; they cannot be reduced but may be increased" is the legal technical equivalent of this balance.

2.3. Just Cause Termination and Its Serious Consequences: Importance of Period and Form Discipline

Immediate termination with just cause is, by its nature, a type of termination with "serious consequences." Since it determines whether to grant the employee the right to severance pay, completely excludes notice pay, and in some cases may even create compensation liability, doctrine treats just cause termination as an exceptional path. This exceptionalism is also seen in the Court of Cassation's approach to period discipline.

The General Assembly states that the statutory periods for just cause termination are preclusive; if these periods are missed (even if just cause exists), the termination becomes wrongful and may produce the consequences of the employee's severance and notice pay. This is a very critical warning in practice: in the employer's claim of just cause termination, "the date of learning of the event" becomes one of the main facts of the file and is placed at the center of the evidence strategy.

3. Mediation as a Condition for Filing Suit: The Area Where Procedure Determines Substantive Rights

3.1. Scope of the Mediation Condition for Filing Suit

Under Law No. 7036 on Labor Courts, mediation is a "condition for filing suit" in claims for employee/employer receivables and compensation and reinstatement requests. This is a filter mechanism that the court addresses ex officio in the preliminary examination in employee receivable actions. In an action filed without applying to a mediator, the court renders a procedural dismissal without entering into the merits.

This regulation is evaluated in doctrine in two directions: (i) the goal of reducing workload and quickly resolving disputes, (ii) the "precondition" debate regarding the employee's right of access to courts. However, the normative reality is clear: in practice, the first step in labor cases is often the mediation bureau.

3.2. Final Minutes, Definitive Period, and the Obligation to Attach to the Petition

The law makes it mandatory to attach the non-agreement final minutes to the petition. This formal obligation directly affects the lawyer's technique of filing the action: "litigation preparation" cannot be considered complete without managing the mediation process. Moreover, in cases such as reinstatement where the periods are very short (the 1 month + 2 week system), it can be seen that the mediation stage is a strategic stage from the perspective of "time management."

3.3. Suspension of Statute of Limitations and Preclusive Periods: The Most Critical Practical Result

Law No. 7036 regulates that from the application to mediation until the final minutes, the statute of limitations is suspended and preclusive periods do not run. This provision is vital especially in the following disputes:

• "Last minute" applications in items sensitive to statute of limitations such as wage receivables, overtime, and annual leave pay,
• Reducing the risk of "missing the period" in areas with definitive preclusive periods such as reinstatement.

Doctrinally, this mechanism shows that mediation, beyond being a "procedural prerequisite," serves a "time protection" function serving the protection of substantive rights.

4. Burden of Proof and Evidence Strategy: Where Labor Cases Are Won

4.1. Distribution of the Burden of Proof: The Primary Burden of the Employer in Reinstatement Cases

Article 20 of Law No. 4857 places the burden of proving the claim of valid termination on the employer. If the employee claims that the termination is based on another reason, the employee is obligated to prove this claim. This formula is explained in doctrine as "double-layered proof":

• First layer: the employer presents the validity/proof of the reason for termination.
• Second layer: if the employee claims that the apparent reason does not reflect the truth (for example, union motive, discrimination, retaliation), the employee must strengthen the factual basis of this claim.

Here, evidence strategy determines the fate of the case in most files. Because in labor law disputes, the documentary record is not always ideal; a multi-layered set of evidence is required such as witnesses, payrolls, time sheets, entry-exit records, email/message records, camera recordings, SSI and bank payment records.

4.2. Existence of Termination and Debate on the Terminating Party: Determination as a "Preliminary Issue"

In labor cases, the court often resolves the following "preliminary issue": Who terminated the contract? Does termination actually exist (is it resignation, mutual agreement, absenteeism, de facto termination)?

The emphasis in Court of Cassation decisions on the need to direct and deliver the termination declaration to the addressee technically frames this preliminary issue. Which party manifested the will to terminate directly affects consequences such as notice/severance pay. For this reason, in practice:

• Termination notice/delivery records,
• Warnings,
• Notary public procedures,
• The employer's SSI exit code,
• The employee's objection to absenteeism minutes,

are placed at the center of the evidence map.

4.3. Collective Action, Protest, and the "Proportionality" Test: Exercise of Rights or Grounds for Termination?

Collective actions/protests in the workplace, especially when combined with union processes, constitute one of the areas where the employee's rights need protection. However, as the Court of Cassation 9th Civil Chamber emphasizes, for a collective action to be legally protectable, it must be "proportionate"; must not carry the mere intent to harm the employer; must not lose the character of democratic exercise of rights.

In labor cases, this translates into practice as follows:

• While the employer says "disrupting work, disturbing workplace discipline, abusing trust,"
• The employee establishes the framework of "peaceful action, proportionate protest, union activity."

The court then looks at the duration of the specific event, the form of the action, its effect on production/workplace, the element of violence or damage, and the employer's opportunity to solve the problem with lighter measures. In doctrine, this is often accompanied by "proportionality and last resort (ultima ratio) view": termination is often the last resort in labor law.

5. Mediation–Litigation Structure: A Roadmap for the Practitioner

In labor cases, the "probability of winning" often begins not in the first petition but earlier: the content of the mediation application, correct classification of claim items, distinction between termination-dependent/independent receivables, and correct structuring of calculations as gross/net and periodical steps form the backbone of the file.

In a practical structure, the following order stands out:

1. Clarify the type of dispute: is it reinstatement, receivable, compensation, or union claim?
2. Write the claim items "completely and alternatively" in mediation: (severance + notice + annual leave + wage receivable + overtime + official holidays, etc.)
3. Prepare an evidence inventory: payrolls, bank receipts, time sheets, correspondence, witnesses.
4. Structure the litigation strategy according to the burden of proof: distinguish between the areas the employer must prove and the areas the employee must strengthen.
5. Manage the periods: special periods for reinstatement; the period-suspending effect of mediation; preclusive period risks.

This model is consistent with the "procedural-substantive right integrity" approach in doctrine: being right about an employee receivable alone is not sufficient; the right must be claimed at the right time, through the correct procedure, and with the correct evidence.

6. In Lieu of Conclusion: 5 Critical Points That Determine Success in Labor Cases

1. If termination theory is not correctly structured (who terminated, when did it reach, what type is the termination), the file falls apart.
2. Mediation as a condition for filing suit is no longer merely a formality; it is a tool for period and statute of limitations management.
3. Distribution of the burden of proof determines the language of the petition: the relationship between "claim," "fact," and "evidence" must be disciplined.
4. In collective action/union processes, it is difficult to obtain results without concretizing the "proportionality" and "intent to harm" criteria.
5. The Court of Cassation's approach to termination and notice period makes it mandatory to take into account the fixed/indefinite-term contract distinction.

This article has addressed the theoretical backbone of labor cases (termination + mediation + proof) together, supported by case law. Although in practice each file is shaped by its own facts, when these three axes are correctly structured, the legal skeleton of the case is solidly built and the probability of success increases significantly.
