The applicant was employed by the third respondent (Absa Bank Ltd) since 6 December 2006 as a quality assurance specialist. In February 2015, her manager Edward Africa instructed all team members, including the applicant, to work official hours of 08h00 to 16h30. The applicant had previously worked 07h30 to 16h00 as a special arrangement, but this was withdrawn in 2014 due to late coming. Despite repeated written instructions from Africa in February, May, and August 2015, the applicant refused to comply and continued working 07h30 to 16h00. The applicant had received a final written warning on 9 July 2015 for insubordination related to refusing to participate in a PAP process, which she never challenged. She was charged with insubordination for refusing to obey lawful instructions regarding working hours, found guilty at a disciplinary hearing on 22 September 2015, and dismissed on 25 September 2015. The applicant referred an unfair dismissal dispute to the CCMA. The arbitrator (second respondent) found the dismissal both procedurally and substantively fair and dismissed her claim. The applicant then brought this review application.
