According to the German Federal Labor Court, Germany’s highest court for employment disputes, German employers are not allowed to monitor employees in the workplace without a concrete suspicion of a criminal violation or, in some cases, a serious breach of duty. This means that employer monitoring of an employee’s computer usage without a concrete suspicion, including the use of keylogging software that records all keyboard entries made at a desktop computer does not comply with German data privacy laws. Courts may exclude evidence obtained under violation of German data privacy laws from their proceedings.
