Payment Below Minimum Wage and Equalization

1) Introduction: Wage security, business flexibility, and legal balance

The minimum wage is a concrete instrument of the "fair wage" and "social state" principles enshrined in Article 55 of the Constitution . It is mandatory for protecting the worker's minimum standard of living , preventing informal employment, ensuring accurate social security and tax bases, and guaranteeing industrial peace. Therefore, agreeing on a wage below the minimum wage , or actually paying below the minimum wage , results in invalid consequences; the worker is entitled to differential wages , interest , administrative fines , and social security premium differences .

From the employers' perspective , equalization (Labor Law Article 63) provides legitimate flexibility in response to fluctuations in production ; however, equalization is not a means of reducing wages or eliminating overtime . The basis, duration, proof, and daily/night work limits of equalization are rigorously scrutinized in the Supreme Court's practice. This guide explains the intersection of both areas in detail, including the logic of application , the proof regime , and calculation techniques

2) Legal Framework and Fundamental Principles (In-depth)

Article 55 of the Constitution: The State guarantees that workers receive fair wages commensurate with the work they perform and ensures the determination of a minimum wage. The mandatory nature of the minimum wage stems from this.

of the Labor Law No. 4857 :

Article 32 (Wages): The concept of wages, place/time of payment, payment via bank, payroll and wage slip (together with Article 37). Failure to pay wages on time results in the debtor's default in accordance with Article 34 , which applies the highest interest rate on deposits
Article 34 (Default interest): The highest bank deposit interest rate from the date the wage becomes due . This interest has a punitive/protective nature in favor of the worker
Article 39 (Minimum wage): No wage lower than the determined minimum wage may be agreed upon/paid; any contrary provision shall be invalid .
Article 41 (Overtime/Work Overtime): 50% increased pay or free time for hours exceeding 45 hours . 100% increased pay for public holidays/public holidays.
Article 63 (Working hours and compensation): The basic rule is 45 hours per week ; compensation is generally 2 months , 4 months with the collective bargaining agreement . The limits of 11 hours per day and 7.5 hours at night are absolute .
Article 64 (Compensatory work): This differs from equalization; it involves making up for lost time later in cases of compelling reasons/workplace closures; the 11-hour daily limit is also maintained here.
Article 24/II-e (Employee's justified termination): wages in accordance with the law/contract the employee the right to justified termination and severance pay .
Article 102 (Administrative fines): Administrative sanctions for violations of wage and working hours regulations .

Turkish Code of Obligations (TBK):

Article 27: Contract provisions that contradict mandatory provisions are absolutely null and void.
Article 420: Waivers not drawn up after the termination of the employment relationship are invalid; to the detriment of the employee are limited; and have weak probative value.
General principles: Prohibition of abuse of rights, principle of good faith (Article 2), worker-favorable approach in contract interpretation.

Secondary Legislation:

The Working Hours Regulation and the Overtime Regulation govern the distinctions between equalization and overtime work.
Special arrangements, such as night work and the employment of female workers in night shifts , should be considered; it should be remembered that the 7.5-hour limit is based on occupational health and safety principles.

Social Security/Tax aspect:

The base earnings for premium calculations must meet the minimum wage; underreporting administrative fines, premium discrepancies , and delays .
From a tax perspective, the tax base determined ; underreporting leads to tax risks and administrative penalties.

Fundamental Principle: The minimum wage is a lower limit; it cannot be reduced, postponed, or substituted. Equalization is a technique for distributing time; wage reductions or exceeding limits .

3) Below Minimum Wage Payments: Typology, Mechanism, and Outcomes

The main scenarios encountered in practice are:

3.1. Agreeing on a Nominal (Contractual) Amount

If the basic wage is set below the minimum wage in the contract , the provision is invalid from the outset . The employee claims the difference between the minimum wage and the agreed wage for each month; according to Article 34, the highest deposit interest rate applies. According to Article 27 of the Turkish Code of Obligations, breach results in absolute nullity ; a subsequent defense of "the employee consented" is not valid.

3.2. De Facto (At the Time of Payment) Liability

Even if the payslip shows the minimum wage, if the bank statement and actual payment indicate that the employee less, they are entitled to the difference. Defenses such as "I deducted it as a cash advance" proven ; undeclared payments make proof more difficult and are interpreted against the employer.

3.3. Substitution with Same Benefits (Food/Service, etc.)

In-kind benefits such as meals, transportation, fuel, and food vouchers do not, as a rule, substitute for the basic wage . The minimum wage must be provided in cash . Otherwise, a difference in wages and social security contributions will arise. In practice, the approach of "meal voucher + transportation allowance + service = minimum wage" is problematic .

3.4. Supplementary Incentives – Variable Wage Models

Cash and regular bonuses/incentives can be considered part of the wage; however, payments that are entirely at the employer's discretion and irregular do not fulfill the guarantee function of the minimum wage. A difference in the minimum wage arises in months when bonuses are not paid or are paid in insufficient amounts . The criteria must be objective and in writing

3.5. Unjustified Deductions/Net-to-Gross Manipulation

Deductions without legal basis, such as advances, cash shortages, and penalties for "erroneous sales," are restricted even with the employee's consent, in light of Article 420 of the Turkish Code of Obligations and mandatory rules. If such deductions reduce the employee's net income below the minimum wage, the difference plus interest becomes a liability.

3.6. Notification under SGK/Tax

Payroll discrepancies and reporting earnings below the minimum wage can result in administrative penalties and late payment fines from the Social Security Institution (SGK); deficiencies in the tax base are also risky. Calculations for items such as severance pay and notice pay, which are in favor of the employee, are also based on the actual wage .

Conclusion: In every instance, the worker can claim differential wages plus interest under Article 34 ; furthermore, the right to justified termination (Article 24/II-e) may arise.

4) Components of Wage: Basic Wage, Gross Wage, Fringe Benefits

Basic wage: This is the cash wage item that must be shown on the payroll and is directly related to the minimum wage guarantee function .
Gross wage: recurring benefits (such as regular bonuses, travel and meal allowances ). It is commonly considered in employee compensation calculations.
Fringe benefits: In-kind benefits such as meals and transportation ; these cannot substitute for the basic salary , but may be considered part of the salary if converted into regular cash payments in the contract
Performance/sales bonus: the criteria are measurable and predictable , it is part of the wage; the mere phrase "at the employer's discretion" is not sufficient on its own.

Practical rule: The base salary on the payroll must always be ≥ the minimum wage ; any remaining benefits can be added to the salary , not substituted for it .

5) Equalization (Article 63): Purpose, Basis and Limitations – Implementation Guide

The goal a 45-hour work week the semester average . For example, if employees work 50 hours one week and 40 hours the next, and the two-week average remains at 45 hours , overtime may not be required.

Duration:

Rule: Equalization within 2 months
Collective bargaining agreements allow 4 months of .
Longer equalization periods are only possible through special arrangements (e.g., different regimes in tourism/maritime industries).

Required documents and process:

Written plan and shift schedule,
Predictability and prior notification,
Maintaining complete and accurate attendance and time sheet records
Break timesshould also be shown (they are often omitted in practice),
UBGT/official holiday work independently .

Absolute limits (independent of the term average):

The daily limit cannot exceed 11 hours .
Night shifts cannot exceed 7.5 hours .
Break times are not included in working hours ; however, actual working hours should be planned so as not to exceed 11 hours.
Even if an average of 45 hours per week is maintained, exceeding the absolute limits mentioned above will result in overtime

Equalization ≠ Zeroing out overtime: Equalization the weekly total ; daily/night limits . An invalid setup cannot be corrected with a "post-equalization defense."

6) Equalization – Minimum Wage Intersection: Common Mistakes and Correct Concepts

Myth 1: “There’s equalization, so I can pay less than the minimum wage.”
→ No. Equalization the time ; the wage cannot fall below the minimum wage.

Myth #2: “I make them work 60 hours a week, then 30 hours the next week; no problem.” → Partially incorrect. Even if an average of 45 hours is achieved , if 11 hours are exceeded daily within a 60-hour week , the excess is considered overtime . The 7.5-hour limit for night shifts is also maintained.

Myth 3: “I’m supplementing the fee with a meal/service card.” → As a rule, this is not possible. In-kind benefits cannot substitute for the base fee .

Correct structure:

Planned equalization period (2/4 months)
Written shift work + timekeeping + bank/payroll compliance
Strict adherence to the 11 hours/day and 7.5 hours/night limits.
UBGT/Public holidays have separate fees.

7) Proof, Evidence, and Trial Strategy (Expanded)

Burden of proof: According to Article 190 of the Code of Civil Procedure, everyone is obligated to prove their claim. However, in labor law, interpretations in favor of the employee and the employer's record-keeping obligation, the actual burden often on the employer .

Main evidence:

Payroll and Wage Slip (Article 37): A payroll signed by the employee without reservation creates a presumption in favor of the employer ; however, this can be refuted by bank statements , timekeeping records , emails , security camera footage , and witness testimonies .
Bank statements: Payment via bank is essential. Bank statements of actual payment ; more authoritative .
Timekeeping/Shift schedules: These document the existence of equalization, compliance with daily/night limits , and overtime claims.
Internal circular/Collective Bargaining Agreement: Indicates the written basis of the equalization regime.
Social Security Institution (SGK) records/e-Government service statements: These reveal discrepancies between actual wages and earnings subject to social security contributions and the payroll records.
Electronic traces: Email timestamps, system login and logout logs, and mobile field applications (courier, sales teams) are indirect evidence of working hours.

Judicial practice:

The expert the equalization period using weekly and daily/night filters; the 11-hour/day and 7.5-hour/night overruns the timeline .
Interest regime: Interest according to Article 34 on wage claims ; legal interest on items such as overtime/subject to interest (unless otherwise stipulated in the contract).
Statute of limitations: 5 years for claims such as wages, overtime pay, etc. Each month becomes due and payable separately; interest starts accruing separately each month.

8) Calculation Logic: Step-by-Step Formulas and Examples

A. Difference Fee Calculation (Monthly):

The minimum base wage (net/gross distinction depends on the specific case) is determined.
The base salary on the payslip is determined.
The cash payment received by the employee (bank) is compared with the payslip.
cash and regular bonuses/incentives, they are added to the salary (in-kind benefits are not included).
Minimum wage – (basic wage + cash/regular additional payments) = Wage Difference.
Interest: Article 34, the highest deposit interest rate, effective from the payment date of each month .

B. Equalization – Overtime Analysis:

term : 2 months (4 months with collective bargaining agreement).
Add up the total hours per week; check your target of 45 hours on average
Apply the 11-hour daytime and 7.5-hour nighttime limits daily
The parts that were vaccinated → overtime (Article 41, 50% raise).
Public holidays/official holidays are separate: 100% pay or leave according to relevant regulations.
If there is a request/application for free time, check the written approval and duration rules.

C. Night Shift Example:

If the 22:00–06:00 shift is 8 hours, any 0.5 hours exceeding 7.5 hours counts as overtime; even if an average of 45 hours is achieved, the night shift limit is absolute, increased pay .

D. Part-Time Work:

If the contract specifies a 30-hour work week, the minimum wage proportionally (30/45). However, if the employee is actually working full-time, the total and actual hours are separated; differential pay and overtime may arise.

9) Night Work and Occupational Health and Safety Aspects – Resistant to Equalization Boundaries

The night shift generally 20:00 and 06:00 (regulations may have different definitions). The 7.5-hour limit occupational health and safety ; it cannot be exceeded through compensation. female night shift workers, young workers , and employees with disabilities . Documentation (health surveillance, transportation/service options, shift rotation intervals) is critically important during inspections.

10) Risk Analysis and Sanctions: Legal, Administrative and Financial Consequences

Wage difference + interest under Article 34: Calculated monthly; interest accrues from the due date of the wage.
Administrative monetary penalty (Article 102): This comes into play in cases of underpayment of wages, payroll violations, and violations of working hours regulations.
Social Security Institution (SGK) differences and penalties: Underreporting of earnings subject to contributions; late payment interest and administrative sanctions.
Justified termination and compensation: If an employee terminates their employment in accordance with Article 24/II-e, severance pay .
Risk of mass disputes: The same practice creates cumulative risk for hundreds of workers ; a wave of mediation/litigation and media reputational damage.
Audits/inspections: In ministry and social security audits, the payroll, bank, and timekeeping systems is critical.

Risk matrix (summary):

Payroll < Minimum → High risk (difference + interest + VAT + Social Security)
Payroll = Minimum Wage, Bank < Payroll → Very high risk (suspicion of undeclared work)
There is compensation, 11 hours/night exceeding 7.5 → High risk (overtime pay required)
Substitution with the same benefit → High risk (difference + social security)

11) Contracts, Internal Regulations and Compliance Procedures (Extensive Templates)

11.1. Minimum Wage Guarantee (Contractual Clause)

“An employee’s basic monthly wage cannot be less than the current minimum wage . Benefits in kind such as meals, transportation, fuel, etc., do not substitute for basic wages . Cash and regular bonuses/incentives are linked to objective performance criteria; they are shown as separate items on the payroll and paid through a bank .”

11.2. Equalization Procedure (Internal Guideline)

“The equalization period is applied as 2 months ( 4 months with the collective bargaining agreement ). Shift schedules are announced in writing and notified to the worker in advance . The limits of 11 hours per day and 7.5 hours at night are absolute . Public holidays/public holidays are not included in the equalization ; the increased wage/leave rules in the legislation apply for these days. Break times are shown separately. All time sheets and schedules are kept for 5 years .”

11.3. Payroll-Bank Reconciliation Procedure

“Payroll and bank statements are matched every month ; HR corrects any discrepancies immediately . Pay slips are delivered with electronic signatures ; the system allows employees to add reservations if they wish .”

11.4. Premium Transparency Policy

“Incentive/bonus criteria measurable, in writing , and predictable . Completely discretionary and irregular payments substitute for the minimum wage .”

12) Mediation, Litigation and Enforcement Strategy (Detailed Roadmap)

12.1. Mediation

Application scope: Difference pay, overtime, UBGT (Unemployment Benefit Guarantee Fund), bonus, annual leave, seniority/notice pay (if applicable).
Attachments: Calculation sheet, payroll-bank reconciliation, timekeeping samples, correspondence.
Strategy: For the employer, early settlement often reduces the total cost; for the employee, interest and litigation time are taken into account.

12.2. The Case

Basis: Articles 32, 34, 39, 41, and 63 of Law No. 4857; Articles 27 and 420 of the Turkish Code of Obligations; secondary legislation.
Claim items: Difference in wages, interest under Article 34; overtime/UBGT increases; bonus differences; severance pay/notice pay, if any.
Expert analysis: Weekly/periodical timeline analysis + absolute limits filter.
Proof: of the payroll presumption bank statements and reservations; supported by timekeeping, turnstile, and email traffic data.
Statute of limitations: 5 years; each month becoming due separately.

12.3. Enforcement

Collection through court-ordered enforcement (court/IB agreement) is rapid; the collectibility of employee receivables is high due to their privileged nature

Conclusion: A well-designed equalization system leads to a secure wage regime

Paying below the minimum wage has multifaceted consequences , not just wage differences, but also interest , administrative fines , social security contributions , and justifiable termination . Equalization , on the other hand, is a time management tool ; it is not a tool for reducing wages or waiving overtime . The key to success is payroll-bank alignment , a written equalization plan , adherence to absolute hour limits , and a transparent bonus policy .
