What is Collective-agreement penalty (multa convencional)?

A collective-agreement penalty is the sanction agreed in a collective instrument for breaching its clauses. Negotiated in a collective bargaining agreement (art. 611 of the CLT), it works as a penalty clause: it encourages compliance and indemnifies breach. Súmula 384 of the TST allows a single penalty per instrument, even if several clauses are breached, unless otherwise provided.

Its ceiling is the value of the principal obligation (art. 412 of the Civil Code). In portfolios with a strong union presence it is a recurring claim — modest in individual value, but accumulating across the portfolio.
