Supreme Court dismissed appeal; employer's discretionary bonus claim failed due to collective agreement restrictions on management remuneration.

The Supreme Court dismissed the plaintiff's cassation appeal regarding unpaid discretionary bonuses for the board chairman. The lower courts ruled that the bonus was discretionary and depended on the Supervisory Board's approval, which was never granted during the disputed period. The Supreme Court upheld this decision, noting that the collective agreement explicitly prohibited setting remuneration rules for persons managing the employer, rendering the bonus agreement unenforceable.
