Questão jurídica principal
Whether contractual salary supplements must be included in the normal wage used to calculate overtime pay under Art. 321c CO.
Decisão extraída
Yes. Contractual supplements forming part of the agreed remuneration count as normal wage for overtime calculation unless a valid written derogating agreement excludes them.
Fundamentação extraída
The company rules provided only for overtime supplements but did not clearly exclude the premiums from the wage base. The bonuses for inconvenience, driving, seniority and responsibility were part of the agreed salary.
