Representative trade union organisations may take all legal action resulting from the provisions of this Title on behalf of an employee without having to prove that they have a mandate from the person concerned.
All that is required is that the employee has been notified, under conditions determined by regulation, and has not objected within a period of fifteen days from the date on which the trade union organisation notified him of its intention.
The person concerned may always intervene in the proceedings initiated by the union and terminate them at any time.
