Traditionally, collective conflicts terminated with the subscription of a Collective Bargaining Agreement (total agreement scenario) or with an Arbitral Award (when there is no agreement and an Arbitral Court is incorporated). However, recently, unions have opted to withdraw the petition sheet before the Collective Bargaining Agreement is entered into or the Arbitral Award is in force, to terminate the collective conflict. Our legislation does not establish if unions can withdraw the petition sheet and, therefore, the validity and effects of such conduct. Is there a legislative omission on the withdraw the petition sheet? If the answer is affirmative, is the omission absolute or relative? Even though these questions have not been answered from the academy or court ruling, the Ministry of Work and our Courts have interpreted that this conduct is valid and that its effect is to terminate the collective conflict. The Court’s thesis is that: (i) as this conduct is not forbidden in our legislation, it is allowed; and that (ii) the negotiation right of unions implies discretion and therefore, the possibility of revoking the proposals submitted in the petition sheet, must remain. In practice, this has allowed unions to file a petition sheet, certain stages take place and then unions withdraw the petition sheet, eliminating all progress and having been protected against dismissal by circumstantial protection; and then, again, they can file another petition sheet (even with the exact the same articles), the stages of the law take place and they can withdraw it again having enjoyed circumstantial protection again; and so on. The lack of pronouncement on the limits to the withdrawal of the petition sheet has allowed unions to maintain different collective conflicts on the same points and, therefore, the prolongation of the circumstantial protection between one and other collective conflict without reaching a Collective Bargaining Agreement or an Arbitral Award that terminates the collective conflict and generates stability and certainty during a specific period. Therefore, it is worth asking whether submitting a petition sheet, withdrawing it and presenting it again, preserving the circumstantial protection, constitutes an abuse of the negotiation right. How legitimate is to file a petition sheet, withdraw it, submitting it again, withdraw it and so on? Is it really a negotiation strategy or a way to prolong the circumstantial protection and wear down the employer? Are we facing a new form of carousel?
