Labor Law is the umbrella law that regulates labor relations in the Republic of Croatia, and it is harmonized with the legal acquis of the European Union in the field of labor legislation.

The Labor Law provides for freedom of contract, which means that the employer, worker and workers' council, as well as trade unions and employers' associations, can agree on working conditions that are more favorable for the worker than the conditions specified by the law itself.

Every employer who employs more than twenty workers is obliged to bring and publish Regulations on work which regulates wages, work organization and other issues important for workers employed by that employer, if these issues are not regulated by a collective agreement.

Temporary employment of workers through the agency for temporary employment is also regulated by the provisions of the Labor Act. The agency for temporary employment, as an employer, assigns workers to another employer for temporary performance of work on the basis of a contract on the assignment of workers.
