Question juridique clé
Whether the 2002 bonus was a discretionary gratification or part of salary under the employment contract.
Solution extraite
The bonus was an element of salary, not a mere gratification, because of its regular payment, size relative to salary, and link to performance objectives.
Motifs extraits
The employer's reservation of discretion was ineffective given the consistent practice, the substantial and recurring amounts, and the objective performance-based remuneration system.
