With the decision of the Competition Board dated 14.08.2025 and numbered 25-31/714-M, an investigation has been initiated to determine whether certain undertakings, associations of undertakings and a consulting firm operating in the shipbuilding sector violated article 4 of the Act no 4054 on the Protection of Competition (the Act no 4054) according to article 41 of the same Act. 
As a result of the information and documents obtained and examinations made during the preliminary inquiry, it was found that the suspicions about restriction of competition were significant. Within this framework, the subject of the investigation about 33 undertakings, two associations of undertakings and a consulting firm operating in the sector is the claim that whether article 4 of the Act no 4054 has been violated through

• exchanging competitively sensitive information,
• wage fixing,
• engaging in no-poaching agreements,
• facilitating the formation and maintenance of such agreements.

Exchanging competitively sensitive information and wage fixing agreements in the labor markets result in fixing the price of labor input whereas no-poaching agreements lead to the restriction of labor mobility and thus violate the Act no 4054.
