Under the Works Constitution Act, every employee has the right to complain to the responsible bodies in the company. Wegen der Erhebung einer Beschwerde dürfen dem Arbeitnehmer keine Nachteile entstehen. Making a complaint must not cause the employee any disadvantage. The works council must also accept complaints from employees. On safety at work, the Occupational Safety Act lets employees make suggestions on every question. If they have concrete reasons to believe that the safety measures are not enough, and the employer does not deal with their complaints, they may turn to the responsible authority, again without disadvantage.
