The regulations mentioned in collective agreements generally concern hours of work. These topics are, for example, working time balancing systems in shiftwork, remuneration for shiftwork and weekly days off. Congress passed the National Labor Relations Act (NLRA) (29 United States) in 1935. C.A. §§ 151 et seq.) to define employees` right to collective bargaining and other group activities (§ 157). The NLRA also established the National Labour Relations Board (NLRB), a federal body empowered to uphold the right to collective bargaining (Article 153). The NLRA has been amended several times since 1935, including in 1947, 1959 and 1974. In Finland, collective agreements are of general application. This means that a collective agreement in an industry becomes a universally applicable legal minimum for the employment contract of each individual, whether a member of a union or not.
Second, the conclusion that subcontracting is a matter of compulsory bargaining brings about the objectives of the NLRA by « bringing a problem of vital interest for work and management within the framework established by Congress as the most conducive to industrial peace » – namely collective bargaining. Third, other employers in the same industry have raised the issue of procurement in the bargaining process, rather than leaving it to management`s discretion.
