One of indisputable freedoms of labor unions is the freedom of coalition. Under Labor Unions Act, full right to coalition consists of: freedom to establish labor unions and freedom to join existing labor unions. In Poland some social and labor groups were deprived of the freedom of coalition (full or even limited), which is not consistent with international and European law. Granting them at least limited right of coalition would correspond to art. 1 of the Labor Union Act that defines labor unions as organizations of people who perform work, not only those who are employed. Thus, the law-maker’s actions should aim at expanding the subjective scope of the freedom of coalition through abolition of numerous restrictions related to that freedom in order to adjust Polish national solutions in that area to international and European law. Still not all entitled persons use the freedom of coalition in full, or even limited scope.
