Member States shall ensure that there are effective mechanisms through which third-country nationals in illegal employment may lodge complaints against their employers, directly or through third parties designated by Member States such as trade unions or other associations or a competent authority of the Member State when provided for by national legislation.

Member States shall ensure that third parties which have, in accordance with the criteria laid down in their national law, a legitimate interest in ensuring compliance with this Directive, may engage either on behalf of or in support of an illegally employed third-country national, with his or her approval, in any administrative or civil proceedings provided for with the objective of implementing this Directive.

Providing assistance to third-country nationals to lodge complaints shall not be considered as facilitation of unauthorised residence under Council Directive 2002/90/EC of 28 November 2002 defining the facilitation of unauthorised entry, transit and residence13.

In respect of criminal offences covered by Article 9(1)(c) or (e), Member States shall define in national law the conditions under which they may grant, on a case-by-case basis, permits of limited duration, linked to the length of the relevant national proceedings, to the third-country nationals involved, under arrangements comparable to those applicable to third-country nationals who fall within the scope of Directive 2004/81/EC.
