Section 16 of the German Occupational Safety and Health Act obliges employees to report, without delay, every immediate and significant danger they notice and every defect in the safety systems. Especially in nursing and health care, staff use a related notice, the Überlastungsanzeige, the overload notice. They write it when the work can no longer be done properly and harm is threatened. No set form is needed. Der Beschäftigte muss darin nur klar darstellen, warum die Situation so gefährlich ist. The employee only has to state clearly why the situation is so dangerous. After the notice, responsibility lies with the superior, and as a rule the employee cannot be held liable. The notice never permits the employee to work improperly.
