Section 2. Basic concepts. The term „collective agreement“ means a legal act regulating the employment, socio-economic and professional relations between the employer and the workers of an undertaking, institution or organisation (hereinafter referred to as „undertaking“). The number of work stoppages per agreement is calculated by dividing the annual number of work stoppages by the number of counts. In most cases, collective bargaining takes place between employers` organisations or individual employers, on the one hand, and trade unions, on the other. Each agreement is signed by the most representative union in the company or sector, defined as the union with the largest number of members with the right to vote. Prohibition of acts which impede the conclusion, revision or application of collective agreements or agreements. The organs of the board of directors and management, political parties and any employers` organisation shall be prohibited from intervening in any way in order to restrict the legal rights of workers or their representatives or to impede the exercise of those rights when concluding, reviewing and applying collective agreements and agreements. At the national level, there are a number of tripartite bodies that bring together trade unions, employers and government, such as for example. B organisations covering unemployment insurance and sickness insurance. .
