Willie Rahl (fourth respondent) was employed by Telkom SA SOC Limited for 36 years from 1982 to 2018 as a supervisor in the Open Serve business. He was dismissed on 5 February 2018 for gross dereliction of duty. Telkom preferred five main charges against Mr Rahl, all relating to failures to supervise and manage his subordinates properly: overtime mismanagement (permitting employees to claim overtime not due), failures in dispatch management, failures in fleet management, TBI process management failures, and inappropriate time management of subordinates. In the disciplinary enquiry, Mr Rahl was found not guilty of several charges; where guilty, he received sanctions ranging from a final warning to dismissal. The sanction of dismissal applied to two overtime mismanagement charges, one dispatch management charge, all fleet mismanagement charges, and both time management charges. Mr Rahl referred a dispute concerning the fairness of his dismissal to the CCMA. At the arbitration, Telkom led a single witness (Mr Senoamadi, the disciplinary enquiry chairperson) and Mr Rahl testified in support of his application for relief.
