Article 22(2). General working conditions shall be determined by law, supplemented by collective labour agreements concluded through free negotiations and, in case of the failure of such, by rules determined by arbitration. [...] Article 23 (1). The State shall adopt due measures safeguarding the freedom to unionise and the unhindered exercise of related rights against any infringement thereon within the limits of the law. (2). Strike constitutes a right to be exercised by lawfully established trade unions in order to protect and promote the financial and the general labour interests of working people. Strikes of any nature whatsoever are prohibited in the case of judicial functionaries and those serving in the security corps. The right to strike shall be subject to the specific limitations of the law regulating this right in the case of public servants and employees of local government agencies and of public law legal persons as well as in the case of the employees of all types of enterprises of a public nature or of public benefit, the operation of which is of vital importance in serving the basic needs of the society as a whole. These limitations may not be carried to the point of abolishing the right to strike or hindering the lawful exercise thereof.
