ABSTRACT
According Constitution article 54/1 if a disagreement arises during the collective bargaining process, workers have the right to strike. Regulations which are related to right to strike is also held in Law on Trade Unions and Collective Labour Agreements. In our legal system, workers only strike in the event of a dispute during negotiations to make a collective labour code to protect and improve their economic and social rights and also working conditions. If the conditions for lawful strike is not fulfilled, the strike becomes unlawful. On the other hand, collective actions, which are not regulated in our Law on Trade Unions and Collective Labour Agreements, are recognized by Turkish Supreme Court in the light of decisions of European Court of Justice and other international agreements. According to Constitution article 90/5 “In the case of a conflict between international agreements, duly put into effect, concerning fundamental rights and freedoms and the laws due to differences in provisions on the same matter, the provisions of international agreements shall prevail. Collective actions must be examined in the context of international law. In our study, firstly the right of strike and collective actions are examined and then three different Supreme Court decions will be held
