The applicant, a transport company, employed Mr Mkhwanazi (third respondent) as a driver of Tautliner trucks on long distance trips. On 6 March 2017, he attended a disciplinary hearing for reckless driving and received a written warning. After the hearing, he was asked to drive or accompany a side tipper truck driver, which he refused, stating he didn't have his driver's licence as he hadn't expected to drive that day. The following day, he was again asked to become familiar with the side tipper truck operation and refused. This refusal led to his dismissal for insubordination. There were significant differences between Tautliner and side tipper driving positions: Tautliner drivers were paid monthly with higher remuneration and received sleep-out allowances for overnight trips, while side tipper drivers were paid weekly at lower rates for local trips. Mr Mkhwanazi alleged the employer intended this as a punitive change to his conditions of employment without his agreement. The employer's owner allegedly told Mr Mkhwanazi he would be forced to drive the local truck and would not be allowed to sleep in the truck, requiring him to return home daily despite living far away.
