Quantification of damages requires the court to determine and express specific monetary amounts for each head of claim, not merely list categories of damages. A court order must be sufficiently clear and specific to stand on its own for enforcement purposes, stating exact figures rather than referring to the body of the judgment. The employee bears the onus of proving his claims with specific evidence and amounts. Awards of damages must have a proper legal basis - for example, bonuses are generally discretionary and depend on performance; commission requires proof of actual sales; and certain benefits (use of car, shares, office furniture) may not be claimable by a dismissed employee. Where the court fails to properly execute its mandate through judicial error rather than fault of either party, no costs order should be made.
