Staff members may always contact the local employer representative directly if they feel that they are being disadvantaged, treated unfairly or in any other way affected by their specialist or operational superior. This applies also for senior staff members who feel they are in such a situation in their role as a superior. You may also involve a member of the Works Council to provide support or act as a mediator (§ 84 of the Works Constitution Act).
The role of the employer representative is usually performed by the Managing Director. If they consider the complaint to be justified, they are obliged to take action to remedy the situation (§ 84 of the Works Constitution Act). If the Managing Director is affected themselves, there are further points of contact, which are also bound to confidentiality.
