It is an opportunity for the unemployed to find temporary work. For those entering the labour market, it is an opportunity to gain essential experience in a range of companies. It is also a convenient solution for those who cannot work full time. It should be noted that many employers choose to hire a permanent employee after a period of temporary employment. Employment under a temporary employment contract is a tripartite contract, i.e. three entities are involved: employee leasing - it is the formal employer, calculates and pays wages and due social security and tax contributions employee - performs work under a temporary employment contract user employer - the company where the employee performs work. A temporary employment contract is a contract with full responsibilities for both the employer and the employee. It guarantees compulsory insurance like a regular employment contract, employee health checks, and health and safety training. The time spent working under a temporary contract counts as length of service and will be taken into account when calculating a pension. Temporary work is, by definition, temporary work and therefore, according to the Act of 9 July 2003 on the Employment of Temporary Workers, the total period of employment of a temporary worker with one user employer cannot exceed 18 months in any consecutive 36-month period.
