Guide to Termination in Employee-Employer Disputes: Do Not Lose Your Rights When Submitting a Resignation Letter!

Comprehensive Guide to Labor Law: Foundations of Employment Relationships, Termination Processes, and Labor Receivables
Labor Law is a specialized branch of law characterized by its unique procedures and distinct dynamics, directly impacting the widest segments of society. While its foundational core rests upon the protection of the employee, it simultaneously balances the employer’s management rights and the operational continuity of the enterprise. As Malgır Law Firm, we analyze in depth the statutory boundaries of the employee-employer relationship, the categories of termination, and particularly the critical errors committed during resignation processes, in light of the Labor Law No. 4857 and settled jurisprudence of the Court of Cassation.
1. The Foundation of the Employment Relationship: Employee, Employer, and Mutual Obligations
Pursuant to Article 2 of the Labor Law No. 4857, a natural person who performs work based on an employment contract is defined as an "employee" (işçi), a natural or legal person who employs an employee is defined as an "employer" (işveren), and the legal bond established between these parties is termed an "employment relationship" (iş ilişkisi).
The employment relationship imposes strict legal obligations upon both parties:
Obligations of the Employee: Personally executing the performance of work, complying with the lawful instructions of the employer, and most crucially, safeguarding the employer’s commercial secrets and refraining from actions contrary to integrity and loyalty under the "duty of loyalty" (sadakat borcu).
Obligations of the Employer: Paying the wage—which constitutes the most fundamental right of the employee—fully and on time, adhering to the principle of equal treatment, protecting the employee's well-being, and implementing occupational health and safety measures without deficiency.
Golden Rule: The Principle of Interpretation in Favor of the Employee
In Labor Law, protecting the weaker party is a fundamental tenet. Therefore, in the event of a statutory or contractual lacuna, ambiguity, or contradiction, the Labor Courts and the Court of Cassation directly interpret the relevant rules "in favor of the employee" (işçi lehine yorum ilkesi). The burden of proof rests heavily upon the employer in most disputes.
2. Concepts of Termination: The Sharp Line Between Valid Reason and Just Cause
There are two distinct legal paths for the dissolution (termination) of an employment contract by either the employer or the employee. Confounding these two concepts can lead to devastating financial losses in terms of statutory compensations. All circumstances prescribed by law are detailed below:
A. Termination for Valid Reason (Termination with Notice - Article 18)
This occurs when the employer terminates the employment contract based on reasons that do not possess the gravity of immediate dismissal but nevertheless disrupt the ordinary operational workflow of the enterprise. A termination based on a valid reason cannot be executed summarily; the employee must either be granted a statutory notice period or be paid notice pay (ihbar tazminatı) in lieu. Pursuant to Article 18 of Law No. 4857, valid reasons are categorized under three main headings:
Reasons Arising from the Capacity of the Employee: Performance issues, low productivity, unsuitability for the job, or frequent short-term illnesses.
Reasons Arising from the Conduct of the Employee: Actions that do not directly inflict material damage on the employer but breach the operational discipline of the workplace (such as incompatibility, frequent tardiness, or altercations with supervisors).
Reasons Arising from the Requirements of the Enterprise, Workplace, or Job: Economic crises, corporate downsizing decisions, technological restructurings, or the closure of specific departments.
CRITICAL NOTE: If a termination is to be executed based on performance or conduct, it is legally mandatory for the employer to issue prior written warnings and to obtain the employee’s written defense prior to executing the termination.
B. Immediate Termination for Just Cause (Articles 24 and 25)
This is a summary legal remedy invoked when the continuation of the employment relationship becomes entirely intolerable for one of the parties. The statutory notice period is not observed, the contract is dissolved immediately, and no notice pay is due under this type of termination.
Right of the Employee to Immediate Termination for Just Cause (All Circumstances Under Article 24):
I. Health Reasons: The performance of the work becoming dangerous to the employee’s health or life due to the nature of the job; or the employer or another employee contracting an infectious disease incompatible with the work environment.
II. Situations Incompatible with Moral Principles and Good Faith, and Similar Instances:
The employer misrepresenting essential facts or misleading the employee at the time of concluding the contract.
The employer uttering words or engaging in conduct that assaults the honor, reputation, or sexual integrity of the employee or their family members.
The employer assaulting, intimidating, inciting to crime, or leveling severe insults or unfounded accusations against the employee or their family.
The employee being subjected to sexual harassment by another employee or a third party within the workplace, and the employer failing to implement necessary measures despite being notified.
The employee’s wages (including salary, overtime, bonuses, etc.) not being calculated or paid in accordance with the provisions of law or the contract.
In piece-work systems, the employer allocating insufficient work without compensating the wage deficit on a time basis, or failing to apply the agreed fundamental working conditions.
III. Force Majeure: The emergence of compelling reasons requiring the suspension of operations at the workplace for more than one consecutive week.
Right of the Employer to Immediate Termination for Just Cause (All Circumstances Under Article 25):
I. Health Reasons: The employee contracting a disease or suffering a disability due to their own deliberate intent, disorganized lifestyle, or alcohol addiction, leading to absenteeism exceeding 3 consecutive business days or more than 5 business days within a single month; or a medical board determining that the employee's disease is incurable and incompatible with their workplace performance.
II. Situations Incompatible with Moral Principles and Good Faith, and Similar Instances:
The employee misleading the employer by providing false qualifications or inaccurate details at the time of the conclusion of the contract.
The employee uttering words or engaging in conduct that assaults the honor and reputation of the employer or their family, or leveling unfounded and defamatory allegations.
The employee sexually harassing another employee of the workplace.
The employee assaulting the employer, their family, or another colleague; reporting to work intoxicated or under the influence of narcotics, or consuming these substances within the workplace premises.
The employee engaging in conduct incompatible with integrity and loyalty, such as breach of trust, theft, or disclosing the employer’s professional and commercial secrets.
The employee committing an offense within the workplace that is punishable by imprisonment for more than 7 days without a suspension of sentence.
The employee failing to report to work without permission or just cause for 2 consecutive business days, or twice within a month on the business day following a holiday, or for a total of 3 business days in a single month.
The employee stubbornly insisting on not performing their assigned duties despite being explicitely reminded to do so.
The employee endangering workplace safety or causing damage/loss to machinery, installations, or property under their custody to an extent that cannot be covered by the equivalent of their 30-day wage.
III. Force Majeure: The emergence of a force majeure event that prevents the employee from working at the workplace for more than one week.
IV- Custody and Arrest: The period of absenteeism resulting from the employee being taken into custody or arrested exceeding the applicable statutory notice period under Article 17.
3. Statutory Severance Pay: Circumstances of Entitlement and Forfeiture
An employee who has completed at least one full year of continuous service under the same employer qualifies for Statutory Severance Pay (Kıdem Tazminatı).
Circumstances of Entitlement: Dismissal by the employer based on a "valid reason" (Article 18), summary termination executed by the employee for "just cause" (under Article 24, e.g., non-payment of wages), retirement, mandatory military service, or voluntary resignation by a female employee within one year from the date of her marriage. Severance pay is also due if the employer terminates the contract based on health or force majeure reasons.
Circumstances of Forfeiture: If the employer terminates the employment contract immediately for just cause under Article 25/II due to "situations incompatible with moral principles and good faith" (such as theft, assault, insults, or unexcused absenteeism), the employee forfeits all rights to severance pay. Furthermore, if an employee resigns entirely of their own volition without asserting a statutory just cause, their accrued severance pay is completely forfeited.
4. Labor Receivables: The Statutory Remuneration of Labor
In a labor dispute, alongside standard indemnities, the largest financial components are usually composed of unpaid labor receivables:
Overtime Pay (Fazla Mesai): Hours worked exceeding 45 hours per week constitute overtime. The wage for each hour of overtime work must be compensated by increasing the standard hourly rate by 50%.
National Holiday and General Holiday Pay (UBGT): An employee who does not work on official national or public holidays receives their full standard wage for that day. If they are required to work on such holidays, they must be paid an additional full day's wage (resulting in double pay for that day).
Weekly Rest Day Pay (Hafta Tatili): The statutory right to an uninterrupted rest period of at least 24 hours within a 7-day work cycle. If an employee is required to work on their weekly rest day, an additional premium wage must be compensated.
5. Legal Risks of Resignation Letters and the Compliance Criteria of the Court of Cassation
The resignation phase is the most legally volatile domain where employees suffer major losses of rights. Flawed resignation letters submitted under employer coercion or due to a lack of legal awareness can lead to a total waiver of accrued statutory rights.
The "Handwritten" vs. "Template" Approach of the High Court
The jurisprudence of the Court of Cassation is strictly clear: pre-printed, template, or "fill-in-the-blank" resignation forms are highly controversial regarding their validity. The courts generally presume that such documents are signed under administrative duress (irade fesadı). For a resignation letter to be deemed legally valid, it must ideally be written entirely in the employee’s own handwriting and bear their wet signature.
The Pitfall of Stating Reasons and the "Due to Necessity" Strategy
An employee is legally bound by the specific reasons they explicitely state in their resignation letter, and cannot alter these grounds in a subsequent lawsuit. For instance, an employee who writes "I am resigning because I have secured a better employment opportunity" cannot later argue before the court that "I actually left because my overtime wages were not being paid." Such an inconsistency results in the absolute forfeiture of severance pay.
Therefore, instead of outlining concrete and specific reasons during a resignation, utilizing general and broad legal phrases such as "Due to discovered necessity...", "Based on personal reasons...", or "Reserving all my statutory rights for just cause..." constitutes the safest strategic path under the law.
Why is this critical? If an employee leaves using a general phrase and subsequently initiates a lawsuit, and the expert evaluation of workplace records reveals that the employee had outstanding overtime, weekly rest day, or holiday receivables, the court applies the following presumption: "The employee had unpaid statutory receivables; no employee abandons their employment without a valid reason. Therefore, this resignation in fact constitutes a constructive termination for just cause by the employee due to non-payment of wages under Article 24." Consequently, even though the employee appeared to have resigned voluntarily, they successfully qualify for statutory severance pay.
Conclusion
In the administrative and judicial fields of Labor Law, strict adherence to procedure is the sole pathway through which substantive righteousness is certified. Managing human resources and termination processes in full compliance with the law is imperative for corporations, just as avoiding procedural errors is vital for employees seeking their lawful remuneration.
