There has been a breach of security of Deutsche Telekom employees ' personal data , Handelsblatt reported . A company spokesman confirmed a report in Manager Magazin to this effect , and said a limited number of staff members have had access to employees ' personal data that ought to have been kept in anonymous form only . He added that there were no signs that the information had been misused . He said the supervisory board had apologised to staff . An external auditor will be commissioned to investigate the privacy breach , and the works council wants a lawyer to be involved , too . Handelsblatt said this case is embarassing to the company as CEO Rene Obermann has expanded data protection in recent years and even set up a separate directorate for the issue . Three years ago , a former security head was sentenced for participating in illegal spying on journalists and employee representatives on the supervisory board . ;
