Questão jurídica principal
Whether the employer remained bound by the social plan and owed the departure indemnity
Decisão extraída
Yes. The social plan became part of the individual employment contract and its later shortening was not opposable to the employee without express acceptance.
Fundamentação extraída
The plan was a unilateral offer under Art. 6 CO. Because it was communicated so that HR employees could reasonably expect coverage if their own jobs disappeared, acceptance was presumed. The later reduction of validity was a new, less favorable offer requiring express acceptance, which was absent.
