Can a foreign employee keep a Turkish work permit during long-term sick leave? Learn how medical reports, temporary incapacity, social security, employment termination and work permit extensions interact in Turkey in 2026.

A foreign employee who becomes seriously ill or requires long-term medical leave does not automatically lose their work permit in Turkey.

The Ministry of Labour and Social Security expressly states that when a foreigner holding a work permit becomes ill or suffers an occupational accident, the provisions of the relevant legislation apply.

Accordingly, a medically documented absence should be distinguished from termination of employment. If the employment relationship genuinely continues and the work permit remains valid, medical leave does not by itself mean that the foreign employee’s permit must be cancelled.

However, long-term medical leave can become more complicated when it overlaps with work permit expiration, an extension application, prolonged absence from payroll, social security reporting or termination of the employment relationship.

Does Sick Leave Automatically Cancel a Foreign Employee’s Work Permit?

No.

Illness and temporary incapacity are not automatically equivalent to termination.

The Social Security Institution defines temporary incapacity as the period during which an insured person is temporarily unable to work because of illness, occupational accident, occupational disease or maternity, as certified by an authorized physician or medical board.

Therefore, a foreign employee can remain employed even though they are temporarily unable to perform their duties.

The critical distinction is between:

Temporary medical absence while employment continues

and

Termination of the employment relationship.

Is There a Maximum Medical Leave Period for Keeping a Work Permit?

Foreign work permit legislation does not establish a simple rule such as “30 days of medical leave cancels the permit” or “90 days of illness automatically terminates the permit.”

The circumstances must instead be assessed individually.

Important factors include:

• Whether the employment contract remains in force;
• Whether the employee has a valid medical report;
• Whether the work permit remains within its validity period;
• Whether the employer still intends to employ the worker;
• Whether social security records correctly reflect the absence;
• Whether a work permit extension is approaching;
• Whether employment has actually been terminated.

Consequently, the duration of medical leave matters, but duration alone does not determine the work permit’s validity.

What Is Long-Term Medical Leave?

There is no single foreign-work-permit definition of “long-term medical leave.”

In practice, the expression may cover situations where a foreign employee cannot work for several weeks or months because of:

• Surgery;
• Cancer treatment;
• Serious illness;
• Major injury;
• Hospitalization;
• Rehabilitation;
• Occupational accident;
• Occupational disease;
• Repeated medically certified incapacity periods.

The longer the employee remains absent, the more important accurate employment and social security documentation becomes.

Does a Medical Report Protect the Work Permit?

A medical report does not independently guarantee the continuation of a work permit, but it is extremely important evidence explaining why the employee temporarily stopped working.

The Social Security Institution recognizes temporary incapacity where the employee’s inability to work is certified through an authorized physician or medical board.

Employers should therefore avoid leaving a lengthy absence unexplained in employment records.

Can Foreign Employees Receive Temporary Incapacity Benefits?

Potentially, where the social security conditions are satisfied.

For ordinary sickness, the Social Security Institution states that temporary incapacity benefit is payable beginning from the third day of incapacity where the statutory requirements are met.

For sickness-related temporary incapacity benefits, the employee generally must:

• Remain insured when incapacity begins;
• Have at least 90 days of short-term insurance contributions during the preceding year;
• Obtain a medical report from an authorized physician or medical board.

The benefit is generally calculated as half of daily earnings for inpatient treatment and two-thirds for outpatient treatment.

These social security rights are separate from the question of whether the work permit itself remains valid.

What If the Medical Leave Results from an Occupational Accident?

Different social security rules apply.

For an occupational accident, temporary incapacity benefits may be available without the ordinary minimum contribution-day requirement applicable to sickness. The Social Security Institution states that an insured employee suffering temporary incapacity because of an occupational accident can receive benefits for each qualifying day.

The employer must also comply with applicable occupational accident reporting requirements.

A foreign employee’s nationality does not by itself remove these protections.

What If the Employee Develops an Occupational Disease?

An occupational disease also has its own social security framework.

The Social Security Institution identifies temporary incapacity benefits and permanent incapacity income among the rights available in qualifying occupational disease cases.

Where the employee’s ability to work becomes permanently affected, employment, disability and work permit consequences may need to be considered separately.

Does the Employer Have to Cancel the Work Permit During Medical Leave?

Not merely because the employee is medically unable to work temporarily.

The Ministry specifically distinguishes work permit termination procedures from situations in which a foreign worker becomes ill. It states that applicable legislation governs the rights of a foreign worker who becomes ill or suffers an occupational accident while working under a work permit.

Therefore, legitimate medical leave should not automatically be processed as if the employee had resigned or been dismissed.

When Does Work Permit Cancellation Become Relevant?

Cancellation becomes much more important when the employment relationship actually ends.

The Ministry states that employers must notify it within 15 days of the commencement or termination of work and circumstances that may require cancellation of the work permit or work permit exemption.

Accordingly, employers should distinguish carefully between an employee who is temporarily absent because of illness and an employee whose employment contract has actually terminated.

What If the Employee Cannot Work for Several Months?

Several months of medically certified absence do not automatically establish that the employment relationship has ended.

However, the employer should maintain clear evidence concerning:

• Medical reports;
• Employment status;
• Payroll records;
• Social security reporting;
• Expected return to work;
• Work permit validity;
• Any extension application.

A prolonged unexplained absence can create greater compliance concerns than properly documented medical incapacity.

Can the Employer Terminate a Foreign Employee Because of Long-Term Illness?

This is primarily an employment-law question and depends on the circumstances.

Turkish employment legislation contains specific rules concerning termination connected with illness and prolonged absence. An employer should therefore not assume that a foreign employee can be dismissed immediately merely because they have received a long medical report.

Whether termination is legally possible may depend on matters such as:

• Length of service;
• Duration of absence;
• Nature of the illness;
• Applicable notice periods;
• Whether special protection applies;
• Whether the absence results from an occupational accident or disease.

The work permit consequences arise separately if employment is ultimately terminated.

Does the Work Permit Remain Valid If the Employment Contract Continues?

Generally, the existence of continuing employment is a critical factor.

A fixed-term work permit is granted for work in a specific job and workplace under a particular employer.

Temporary inability to perform work because of medically certified illness should not automatically be equated with changing employers or abandoning employment.

However, the permit remains subject to its stated expiration date.

Does Medical Leave Extend the Work Permit Expiration Date?

No automatic extension should be assumed.

For example, if a foreign employee receives a six-month medical report but the work permit expires after three months, the medical report does not itself add six months to the permit.

The employer must still monitor the normal work permit extension deadline.

The Ministry states that an extension application can be filed beginning 60 days before the existing permit expires and must be filed before expiration.

Can a Work Permit Be Extended While the Employee Is on Medical Leave?

Potentially, yes.

Medical leave itself is not listed by the Ministry as an automatic prohibition against filing an extension application.

However, because a fixed-term permit is based on continuing employment with the employer, the application should accurately reflect the employee’s actual circumstances.

For a long-term medically absent employee, useful supporting records can include:

• Medical reports;
• Employment contract;
• Social security records;
• Payroll documentation;
• Evidence that employment continues;
• Expected return-to-work information.

The extension application should not create an inaccurate impression that the employee has been continuously performing ordinary work if they have actually been on documented medical leave.

What If the Work Permit Expires While the Extension Application Is Pending?

The Ministry currently provides an important continuation rule.

Where an extension application was properly filed, the foreigner may continue working during the evaluation period after the existing permit expires for up to 90 days, provided that the work performed and workplace do not change. Rights and obligations arising from the work permit continue during this period.

Where the employee is simultaneously on medical leave, the medical absence should be properly documented.

Does Long-Term Medical Leave Affect Residence Status?

For ordinary work permit holders, work permit validity is also important for residence purposes.

Therefore, the primary concern is usually not the medical report itself but what happens if:

• The permit expires;
• Employment terminates;
• The permit is cancelled;
• An extension is not filed on time.

Foreign employees undergoing lengthy treatment should therefore monitor their immigration status even when they are physically unable to work.

What If the Employee Is Hospitalized When the Permit Is About to Expire?

The employer and employee should not wait for the employee to return to work before addressing the permit expiration.

The Ministry permits work permit extension applications beginning 60 days before expiration.

Accordingly, permit deadlines should be monitored independently from medical leave dates.

What Happens to Social Security During Long-Term Medical Leave?

The employer must ensure that the employee’s absence is reported correctly under social security legislation.

The Social Security Institution recognizes medically certified temporary incapacity and provides benefits under qualifying circumstances.

For foreign employees, consistency is particularly important between:

• Medical reports;
• Payroll;
• Social security declarations;
• Employment records;
• Work permit records.

Incorrectly recording months of medical absence as ordinary unexplained non-working periods can create avoidable problems.

Does Receiving Temporary Incapacity Benefit Affect the Work Permit?

Receiving a lawful social security benefit because the employee is temporarily unable to work does not by itself mean that the work permit has been cancelled.

Temporary incapacity benefit exists precisely because an insured employee may temporarily be unable to perform work while remaining within the social security system.

The work permit and social security issues should nevertheless be managed together.

What If the Foreign Employee Has a Serious Permanent Disability?

Permanent incapacity requires a different analysis from temporary medical leave.

For occupational accidents and occupational diseases, Turkish social security legislation provides mechanisms for permanent incapacity income where the statutory conditions are satisfied.

From a work permit perspective, the employer should then determine whether:

• The employee can return to the original position;
• Duties need modification;
• Another suitable position is available;
• The employment relationship will continue;
• The existing work permit remains appropriate.

A permanent change in occupation or employment structure can create additional work permit issues.

Can the Employee Perform Lighter Duties After Returning?

Potentially.

An employee recovering from serious illness or injury may return under medically appropriate working conditions.

However, if the employee’s actual occupation changes substantially, the employer should consider whether the new role remains consistent with the existing work permit.

A temporary accommodation is different from permanently transferring the foreign worker to an entirely different profession.

Can the Employee Work Remotely During Recovery?

Potentially, if medically appropriate and legally structured.

For example, an employee recovering from surgery may be capable of working from home before being able to return physically to the office.

However, the employer should distinguish between:

• Medical leave during which no work is performed; and
• Remote employment during recovery.

If the employee is officially on medical leave, requiring them to continue working can create employment and social security issues.

Can a Foreign Employee Work for Another Employer While on Medical Leave?

Not under the existing employer’s work permit.

A fixed-term work permit is issued in connection with a particular employer, job and workplace.

Medical leave from Employer A does not convert the permit into authorization to work for Employer B.

In addition, performing another job while officially certified as medically unable to work can create separate social security and employment-law problems.

Can a Foreign Employee Freelance During Medical Leave?

This should not be assumed lawful.

An employer-dependent permit does not automatically authorize independent freelance activity.

Moreover, performing paid freelance services while receiving temporary incapacity benefits or while certified as unable to work can raise additional questions about the medical report and benefit entitlement.

What If the Employee Travels Abroad for Treatment?

Travelling abroad for treatment does not automatically terminate employment.

However, the employee and employer should monitor:

• Work permit validity;
• Passport validity;
• Extension deadlines;
• Medical documentation;
• Expected return date;
• Employment status.

Foreign medical documentation may also need to be evaluated for its legal and social security effect in Turkey depending on the circumstances.

What If the Employee Cannot Return to Turkey Before the Permit Expires?

This requires early planning.

A medical condition does not automatically suspend the expiration date of a work permit.

The employer should therefore review extension procedures before the deadline and determine whether the foreigner’s absence abroad affects the particular application.

Waiting until after expiration can materially change the applicable procedure because the Ministry states that applications submitted after the permit expires are evaluated according to first-application procedures and principles.

Can Long-Term Medical Leave Cause an Extension Application to Be Rejected?

Medical leave alone should not be described as an automatic rejection ground.

However, an extension application may become more complicated if the records suggest that the underlying employment relationship no longer genuinely exists.

Potential warning signs include:

• Employment effectively terminated;
• Employer no longer intends the employee to return;
• Inconsistent social security records;
• Unexplained payroll gaps;
• Expired medical documentation;
• Another employer actually employing the foreigner.

A properly documented genuine medical absence presents a materially different situation.

What Documents Should Employers Keep?

For a foreign employee on long-term medical leave, employers should preserve at least:

1. Current work permit;
2. Employment contract;
3. Authorized medical reports;
4. Hospital documentation where relevant;
5. Temporary incapacity documentation;
6. Social security records;
7. Payroll records;
8. Correspondence concerning the medical absence;
9. Return-to-work documentation;
10. Work permit extension documents.

The objective is to demonstrate clearly that the absence resulted from legitimate medical incapacity rather than undeclared termination.

What Should Foreign Employees Check During Long-Term Illness?

The foreign employee should monitor:

• Work permit expiration date;
• Whether an extension application is necessary;
• Employment status;
• Social security status;
• Medical-report validity;
• Temporary incapacity benefits;
• Expected return date;
• Any communication concerning termination.

Serious illness can understandably shift attention away from administrative deadlines, but missing a work permit deadline can create a separate immigration problem.

2026 Practical Rule for Long-Term Medical Leave and Work Permits

The safest distinction is:

Short medically certified sick leave:
Does not automatically affect work permit validity.

Long-term medically certified leave while employment genuinely continues:
The permit may remain valid, but medical, employment, payroll and social security records should be kept consistent.

Work permit expires during medical leave:
Medical leave does not automatically extend the permit. An extension application must still be handled within the applicable period.

Employment is terminated because the employee cannot return:
Work permit and immigration consequences must then be addressed. Employers have a 15-day notification obligation for termination and circumstances requiring permit cancellation.

Occupational accident or occupational disease:
Additional social security protections may apply, including temporary or permanent incapacity benefits.

The central issue is therefore not simply how many days the employee has been absent.

The more important question is whether the foreigner’s employment relationship and work permit remain legally valid while the medical absence continues.

Frequently Asked Questions

1. Does long-term sick leave automatically cancel a foreign employee’s work permit?

No. The Ministry states that the relevant legislation applies where a work permit holder becomes ill or suffers an occupational accident. Illness itself is not treated as automatic work permit cancellation.

2. Can a foreign employee keep a work permit while hospitalized?

Potentially, yes, provided the employment relationship and permit remain valid. Hospitalization itself does not automatically terminate the permit.

3. Can foreign employees receive temporary incapacity benefits?

Potentially. For ordinary sickness, the Social Security Institution requires, among other conditions, continued insured status, an authorized medical report and generally at least 90 days of short-term contributions during the preceding year.

4. Does medical leave extend the work permit expiration date?

No. The permit should still be extended within the normal application period.

5. Can a work permit be extended while the foreign employee is on medical leave?

Potentially, yes. The employer should document that the employment relationship continues and explain the medically certified absence.

6. What happens if employment is terminated during medical leave?

The work permit consequences must be addressed separately. The Ministry requires notification within 15 days of termination and circumstances requiring permit cancellation.

7. Can a foreign employee work for another company while on medical leave?

Not using the work permit issued for the existing employer. An ordinary fixed-term permit is tied to a specific employer, job and workplace.

8. Can a foreign employee work remotely while recovering?

Potentially, if the employee is medically capable of working and the arrangement is legally structured. This should be distinguished from a period during which the employee is officially certified as unable to work.

9. Can an occupational accident affect the foreign employee’s work permit?

The accident itself does not automatically cancel the permit. Social security protections, including temporary incapacity benefits, may apply.

10. What is the most important issue during long-term medical leave?

Employers should ensure that medical reports, employment status, social security reporting, payroll records and work permit deadlines remain consistent.
