The Labour Appeal Court in IMATU obo Spangenberg v Overberg District Municipality [2024] ZALAC 56 reaffirmed that employers cannot unilaterally alter agreed job descriptions or bypass approved job evaluation systems. The LAC reinstated the arbitration award, finding the Labour Court exceeded its powers by directing the PAC to act outside its mandate. The ruling underscores the sanctity of job evaluation processes and the limits of managerial discretion in labour relations.
