In April 2015, a German employer told its staff by e-mail that internet traffic would be logged. The next day, it installed software on a web developer’s computer. The software recorded every keystroke and took regular screenshots. The data showed some private use during working hours, and the employer dismissed the developer. On 27 July 2017, the Federal Labor Court ruled the dismissal invalid. The employer could not use the keylogger data in court. The court held that such software is allowed only if there is a durch konkrete Tatsachen begründeter Verdacht einer Straftat oder anderen schwerwiegenden Pflichtverletzung, a suspicion of a crime or another serious breach of duty that rests on concrete facts. Monitoring ins Blaue hinein, into the blue, without such a suspicion, is not allowed.
