Temporary assignment (recruitment, personnel services) means that a recruitment agency (transferor) makes its staff (temporary workers) available to another (third-party) employer on the basis of a labour leasing contract.
The temporary workers carry out their work for the third-party employer, but this employer does not become the employer for the temporary workers.
In Austria, temporary assignment is subject to the special labour law regulations of the Temporary Agency Work Act (Arbeitskräfteüberlassungsgesetz or AÜG) and requires official authorisation.

In addition, collective agreements (for blue-collar workers the collective agreement for the supply of temporary workers, and for white-collar workers the collective agreement for white-collar workers in crafts, trades and services) regulate the minimum wage or salary for all temporary assignments.
