Partial performance of a bonus task justifies reducing the bonus rather than denying it entirely.

The Supreme Court reversed the lower court's dismissal of the employee's claim for a performance bonus, ruling that partial completion justifies a reduction rather than total denial. The employee delayed production by one month and achieved only 50% of the sales target, yet the employer did not abandon the project. The court held that these factors constituted valid 'reductors' warranting a proportional decrease in the bonus amount.
