When looking for employment, Employment Agencies or Job Centres are not the only ones to consider. Jobseekers can also use private labour market service providers of their choice to place them in employment. The involvement of private labour market service providers can result in additional opportunities for new employment. The use of a private intermediary is voluntary. Private employment agencies require a business registration and can also demand compensation from job seekers if they are successfully placed in employment. Only contingency fees are permissible. For jobseekers, however, the permissible compensation for jobseekers is limited to a maximum amount (currently up to 3,000 Euros). For certain professions or groups of persons, the current law permits the payment of a fee by employees that is based on the salary for the mediated activity. These are, for example, artists, professional athletes, au-pairs, artists and photographic models. Compensation for training placement services may only be demanded or received from the employer.
