The sector threshold problem of trade unions has been one of the most important problems of Turkish collective labor law and industrial relations for decades. The sectoral threshold, which was regulated as 10 percent with the Collective Bargaining Strike and Lockout Law dated 1983 and numbered 2822, was initially reduced to three percent and then to one percent with the Unions and Collective Bargaining Law No. 6356 adopted in 2012. Nevertheless the one percent threshold has continued to create significant problems due to the increase in the number of registered workers and severe difficulties in union organization. In this article, Provisional Article 6 of the Law No. 6356, which provides exemption from the industry threshold to trade unions with certain conditions, will be discussed and the problems derived by the mechanism of the industry threshold will be examined. The provisional Article 6 remained in force, repeated several times with various amendments, from the date of publication of Law No. 6356 until 2020. The article is not limited to a pure legal evaluation. The mechanism of “exemption” and the problem of the sectoral threshold will also be concerned in terms of industrial relations.
