Mr Vusi Mathonsi, employed by Scaw Metals (Pty) Ltd as a Charge and Mentor and Assistant Administrator, was dismissed following allegations that he physically assaulted his manager, Mr Melodie Segole, on 17 March 2015. Prior to the incident, Mathonsi had been instructed to obtain pre-approval for overtime due to concerns about control weaknesses and possible fraud. Mathonsi failed to comply, resulting in reduced overtime earnings, which caused animosity towards Segole. After the alleged assault, Mathonsi was charged with misconduct and dismissed after a disciplinary hearing. He referred an unfair dismissal dispute to the Metal and Engineering Industries Bargaining Council (MEIBC). The appointed arbitrator found the dismissal procedurally and substantively fair. NUMSA, on Mathonsi’s behalf, applied to the Labour Court to review and set aside the arbitration award.
