The structure of the BSС’s Unified Primary Trade Union Organization (UPT BSC) includes primary trade union organizations from several entities: JSC "Syryevaya Kompaniya" (Raw Materials Company); the Sterlitamak branch of HeidelbergCementRus LLC; the Sterlitamak Polytechnic College; the Sterlitamak Vocational and Technical College; and the Sterlitamak Chemical-Technological College. It also encompasses the primary trade union organizations of BSC’s subsidiaries: Bashkhimtrans LLC, SP Olkhovka LLC, and Ekol LLC.

 The core activities of the trade union include:

• Representing employees' interests within the framework of social partnership at the enterprise, which involves drafting collective bargaining agreements, negotiating their conclusion, amendment, or supplementation with the employer, and monitoring their implementation;

• Participating in the establishment of remuneration systems, tariff rates (base salaries), incentive structures, labor standards, and work-rest schedules within the organization;

• Performing a protective function by continuously monitoring employer compliance with labor legislation, as well as regulations and agreements concerning occupational health and safety;

• Working to improve working conditions, employee health, and general well-being, while overseeing the use of funds allocated for these purposes;

• Protecting the legal rights and interests of trade union members;

• Providing free legal assistance to trade union members;

• Organizing cultural, educational, and fitness/wellness activities, as well as arranging leisure and recreational events for employees and their families;

• Providing financial support to trade union members.

 A Collective Bargaining Agreement is in place to regulate social and labor relations at the enterprise; it covers a broad range of issues, from remuneration and working conditions to compensation payments and employee benefits. Each year, more than 2 billion rubles are allocated to fulfill the terms of the primary document governing social and labor relations between the employer and its employees.

These funds are directed toward voluntary health insurance for staff; inpatient medical care at local healthcare facilities; dental services; wellness programs for employees and company veterans at the "Olkhovka" sanatorium; and targeted financial assistance—including support for those who have recovered from viral infections and related complications. They also support social initiatives for Bashkir Soda Company (BSK) veterans and young employees (such as financial aid upon returning from military service in the Russian Armed Forces, getting married, or having a child). For employees' children, the company provides subsidized vouchers for summer camps and pediatric sanatoriums, as well as gifts for the New Year and the Day of Knowledge (September 1st). The trade union budget also funds cultural events and activities designed to foster an interest in sports and promote a healthy lifestyle.

 The company’s primary trade union organization has repeatedly won the "Best Collective Agreement (in terms of implementation)" and "Best Collective Agreement (in terms of value per employee)" competitions, organized by the Bashkortostan regional branch of the Roskhimprofsoyuz (Russian Chemical Workers' Union). Furthermore, the organization was recognized as a winner in the "Strong Trade Unions – Reliable Socio-Economic Protection for Workers" competition for its high level of social effectiveness and its role in developing social partnerships.

The trade union at BSC has approximately 5,500 members, representing about 63% of the workforce.
