The respondent was employed by the appellant bank as a Health Education Officer. In August 2007, she informed her supervisor that the clinic was overwhelmed due to group growth. She attended training in December 2007 and went on leave in January 2008. Upon her return, she requested a clerk to assist with medical aid forms that had accumulated, but no additional personnel was appointed. The respondent did not specifically inform her superior that medical aid forms for reimbursement had not been filed, only that the department was under pressure. A new manager appointed in June 2008 discovered the unfiled medical aid forms. The respondent was charged with negligence causing substantial loss to the bank under s 10(2) of the Code of Conduct for Banking Undertaking SI 273/2000 (a Category C offence not warranting dismissal). However, the hearing officer found her guilty of gross negligence (a Category D offence) for not submitting CIMAS claims totaling ZW$623 trillion over December 2007 to May 2008, and she was dismissed. The National Employment Council Appeals Board ordered reinstatement, noting lack of prior disciplinary measures and that two people were employed to replace her. The Labour Court dismissed the bank's appeal, and the bank appealed to the Supreme Court.
