Social Security And Labor Law

The right to reinstatement is a legal protection provided to employees covered by employment security provisions whose employment contracts have been terminated by the employer without a valid reason. As a rule, to claim reinstatement, the workplace must employ thirty or more workers, the employee must have at least six months of seniority, and the employment contract must be for an indefinite term. Certain employer representatives who manage the entire enterprise or who manage the entire workplace with the authority to hire and dismiss employees may fall outside the scope of employment security.

When terminating an indefinite-term employment contract, the employer must base the decision on a valid reason arising from the employee’s capability or behavior, or from the requirements of the enterprise, workplace, or job. The notice of termination must be made in writing, stating the cause for dismissal in a clear and explicit manner. Where termination is grounded on reasons related to the employee’s behavior or performance, obtaining the employee’s defense prior to termination is of critical importance, subject to statutory exceptions.

The employee must apply for mediation with a request for reinstatement within one month from the notification of the termination notice. Since this is a statutory limitation period (hak düşürücü süre), missing the deadline may result in the forfeiture of the right to claim reinstatement. During mediation negotiations, reinstatement, employee receivables, and other consequences of termination can be negotiated together. If no agreement is reached, a lawsuit for reinstatement must be filed in the labor court within two weeks from the date the final mediation report is issued. Applying to a mediator in reinstatement disputes is a mandatory legal condition for litigation (dava şartı).

The court examines whether the reason for termination put forward by the employer is genuine, valid, and proportionate. In terminations based on operational or business reasons, whether the decision was actually implemented, whether alternative positions were available for the employee, and whether termination was treated as a last resort (ultima ratio) carry significant weight. In dismissals based on behavior or performance, the court assesses whether allegations are substantiated with concrete evidence and whether proper warnings were issued to the employee.

If the court rules that the termination is invalid and orders the reinstatement of the employee, the employee must apply to the employer within the statutory time frame following the finalization of the decision. If the employer reinstates the employee, compensation for idle time (boşta geçen süre ücreti) and other accrued rights are paid for the period the employee was not employed, within statutory limits. If the employer fails to reinstate the employee despite a timely application, non-reinstatement compensation (işe başlatmama tazminatı) set by the court becomes payable in addition to the idle time wages. Non-reinstatement compensation is determined between four to eight months’ wages, taking into account the employee’s seniority, reason for termination, and specific case circumstances; idle time wages and other financial rights are calculated for a maximum period of four months.

A court order for reinstatement does not execute automatically without further action by the employee. The employee must apply to the employer to resume work within ten business days from the notification of the finalized decision. The employer must then reinstate the employee within one month from receiving the application. Conducting applications and return-to-work invitations through verifiable channels at this stage is essential to prevent potential future disputes.

Mediation is not mandatory in every dispute arising from labor law. However, for a significant portion of lawsuits regarding employee or employer receivables, compensation claims, and reinstatement requests, applying for mediation prior to litigation is a mandatory legal prerequisite (dava şartı). If a lawsuit is filed directly with the labor court without completing the mediation process, it may be dismissed procedurally without an examination of its merits.

An application for mediation is required before filing a lawsuit for employee receivables such as severance pay, notice indemnity, wages, overtime pay, weekend holiday pay, national holiday and general holiday pay, annual leave pay, premiums, and bonuses. Claims asserted by the employer against the employee—such as notice indemnity, training expenses, advances, or compensation for damages arising from the employment relationship—may also fall under mandatory mediation when conditions are met. For reinstatement claims, special attention must be given to the one-month application period starting from the notification of the termination notice.

Applications can be made to mediation bureaus located within courthouses or through relevant electronic systems. The mediator invites the parties to a meeting and conducts negotiations to resolve the dispute through mutual agreement. The mediator does not act as a judge rendering a ruling in favor of either party; rather, they serve as an impartial third party who assists the parties in reaching a resolution by their own free will.

If an agreement is reached at the end of negotiations, the agreed matters are recorded in a settlement agreement. A duly executed settlement agreement is binding and, when conditions are met, enforceable as a court order (ilam niteliğinde belgedir). As a rule, it is not possible to file a lawsuit later regarding matters agreed upon by the parties. For this reason, it is essential that details such as payment amounts, payment dates, return-to-work terms, interest, expenses, and the scope of release (ibra) are clearly specified.

In the event that no agreement is reached, a final report is issued by the mediator, allowing the parties to exercise their right to file a lawsuit. Applicable statutes of limitations must be observed for general employee receivables, whereas a strict two-week period applies for filing a reinstatement lawsuit following the final report. The period from the mediation application to the issuance of the final report tolls statutes of limitations and suspends statutory forfeiture periods (hak düşürücü süreler).

Mandatory mediation does not, as a rule, apply to lawsuits for material and non-material damages arising from occupational accidents or occupational diseases, nor to related determination, objection, or recourse actions. Additionally, certain social security law disputes—such as determination of insurance coverage and service period—fall directly within the jurisdiction of the labor court. Therefore, the requirement to apply for mediation must be determined not by the title of the claim, but by its precise legal nature.

Administrative acts can be issued by the Social Security Institution (Sosyal Güvenlik Kurumu – SGK) across a wide spectrum of matters, including insurance coverage, premiums, retirement, healthcare benefits, occupational accidents, occupational diseases, temporary incapacity allowances, disability, administrative fines, or the collection of institutional receivables. The legal remedies and time limits applicable to these acts vary depending on the nature of the specific action. Therefore, it is essential first to examine which statutory provision the Institution’s decision is based upon, when it was formally notified, and whether an appeal mechanism is specified within the decision itself.

As a rule, appeals must be submitted via a written petition to the social security provincial directorate (sosyal güvenlik il müdürlüğü) or social security center (sosyal güvenlik merkezi) that issued the act. The petition should explicitly state the date and reference number of the contested act, the legal or factual grounds for its unlawfulness, the requested rectification, and all supporting documentation. Depending on the subject matter of the dispute, service breakdowns (hizmet dökümü), payrolls, bank records, workplace documents, medical board reports, hospital records, and institutional correspondence should be attached to the application.

There is no single appeal period applicable to all SGK actions. For instance, administrative fines, premium debts, minimum labor assessments (asgari işçilik tespiti), medical board decisions, and retirement proceedings may each be subject to different procedural rules. While certain actions require an internal appeal to a commission within the Institution, others permit direct recourse to the competent court. Against premium debt notified following a minimum labor audit, an objection may be lodged with the Institution within one month; if the objection is rejected, an application may be filed with the competent labor court within one month from the notification of the rejection decision.

Regarding decisions of the Institutional Medical Board concerning disability or loss of working capacity, objections can be filed alongside medical reports and health records. Such appeals are reviewed by the High Health Board of Social Insurance (Sosyal Sigorta Yüksek Sağlık Kurulu). Sample petition templates for appealing medical board decisions are also published on the SGK official portal.

If an internal institutional appeal is rejected or yields no result, a lawsuit may need to be filed before the labor court, administrative court, or another competent judicial authority, depending on the legal nature of the dispute. While most disputes concerning insurance coverage, retirement, premiums, and social insurance rights are heard in labor courts, distinct judicial avenues may apply to certain administrative sanctions imposed by SGK. Filing a lawsuit in an incorrect court or missing a specific statutory time limit can lead to a total loss of rights; hence, the competent court, application periods, and pre-litigation objection requirements must be determined independently for each concrete action.

Filing an appeal or initiating a lawsuit does not automatically suspend the implementation of SGK acts in every instance. Especially in actions related to the collection of premium debts and institutional receivables, whether an application stays execution depends on the specific regulation. Therefore, when served with a payment order, lien notice, or other collection proceedings, submitting an appeal petition alone may not suffice; whether a separate legal application is required to stay collection must be evaluated.

It is critical to retain the document registration number confirming that the application reached the Institution and to track the process accordingly. The status of the application can be tracked via SGK’s document tracking service, and general information can be obtained through the ALO 170 hotline. However, submitting an information request or complaint via ALO 170 does not replace or toll the statutory written objection or litigation time limits prescribed by law.
