Collective Labor Agreements in Turkey — Istanbul Employment Lawyer
A collective labor agreement (CLA) is a written contract between a workers' union and an employer or employers' association regulating wages, working conditions and social benefits. It is governed by Law No. 6356 on Trade Unions and Collective Labor Agreements and protected by Article 53 of the Constitution. CLA provisions override less favourable terms in individual employment contracts, while more favourable individual terms survive (Law 6356 Art. 36).
Authorization and Bargaining Stages
- Authorization determination: The union must represent at least 1% of workers in the industry branch and more than half of the employees at the workplace (40% at enterprise level) (Art. 41). The Ministry's determination can be challenged within 6 business days.
- Call to bargain: Must be made within 15 days of receiving the authorization certificate, otherwise the authorization lapses (Art. 46).
- Negotiations: To be completed within 60 days of the first meeting (Art. 47).
- Dispute and official mediation: If no agreement is reached, a dispute report is drawn up and an official mediator is appointed (Arts. 49-50).
- Strike / lockout or Supreme Arbitration Board: If mediation fails, the union may call a strike; in sectors where strikes are prohibited, the Supreme Arbitration Board resolves the dispute with final effect (Arts. 51 ff.; implementation deadlines in Art. 60 apply).
Who Benefits? — Solidarity Contribution
A CLA applies as a rule to members of the signatory union. Non-member employees may benefit by paying a solidarity contribution to the signatory union for the period after signature (Art. 39), capped at the union membership fee. The membership date determines which periods' terms apply, which matters greatly in receivables calculations.
Scope: What Does a CLA Regulate?
- Wage increases, bonuses and social benefits (transport, meal, heating, education allowances)
- Working hours, overtime premium rates and leave entitlements
- Job-security provisions on disciplinary boards and dismissal procedure
- Union workplace representatives and their protection (Art. 24)
Dispute Types and Litigation Routes
Interpretation actions (Art. 53) resolve disagreements over the meaning of CLA provisions. Monetary claims arising from a CLA (wage differences, bonus receivables) are subject to mandatory pre-suit mediation (Law 7036 Art. 3). Dismissals connected to union membership trigger anti-union compensation (Law 6356 Art. 25), which cannot be less than one year's wages.
