In June 2021, two Turkish companies, Cengiz İnşaat and CI-AY Mühendislik, were hired to reconstruct a railway section in Croatia. From the beginning of the project, SGH, an affiliate of the Union of Autonomous Trade Unions of Croatia (SSSH) in the construction sector, contacted the management of the two companies to discuss the need to apply the sectoral collective agreement for all the workers working on the reconstruction project, including Turkish workers brought in for the project. The two companies obstinately refused any attempt by SGH to disseminate information to workers.
On 17 February 2022, SGH visited the workers on the construction site during their break and handed them leaflets on the rights under the collective agreement. Workers reported a series of violations of their rights, including working 250-300 hours a month and not being paid overtime. Immediately thereafter, seventeen workers received a text message informing them that they had been fired.
