Performance incentive bonuses payable at the employer's discretion upon achievement of performance targets constitute benefits, not remuneration as defined in the BCEA, and therefore do not fall within the CCMA's jurisdiction under section 74(2) of the BCEA. Alternatively, even if such bonuses were remuneration, section 4(c) of the BCEA ousts CCMA jurisdiction where the contractual term is more favorable to the employee than the basic condition of employment. The proper forum for contractual claims is the Labour Court under section 77(3) of the BCEA. The Labour Court must determine CCMA jurisdictional questions de novo on review. For constructive dismissal, an employee must prove objectively that the employer's conduct rendered continued employment intolerable, leaving no reasonable option but resignation. Senior employees receiving generous remuneration are expected to endure workplace pressures and utilize grievance procedures before resigning.
