The Senate has approved two amendments to the Heritage Petroleum, Paria Fuel Trading and Guaracara Refining Vesting Amendment Bill 2026, paving the way for the Oilfields Workers’ Trade Union (OWTU) to be deemed the recognised majority union for workers at Heritage Petroleum and Paria Fuel Trading for both existing collective agreements and future collective bargaining.
The amendments, which originated in the House of Representatives, were passed following a division in the Senate, with 17 senators voting in favour, six against and seven abstaining.
Piloting the amendments, Leader of Government Business Darrell Allahar said the changes were intended to clarify Parliament’s original intent when the legislation was debated earlier this year.
The first amendment replaces the word “continue” with the words “be deemed” in a newly inserted section of the legislation.
Allahar said the change was being made “out of an abundance of caution” to ensure that the OWTU, which was the recognised majority union representing workers at Petrotrin before its restructuring in 2018, would be deemed the recognised majority union for workers at Heritage Petroleum and Paria Fuel Trading.
He explained that while the OWTU had been the bargaining agent at Petrotrin, the successor companies were created after Petrotrin ceased to exist, making it more appropriate in law to “deem” the union to hold that status rather than state that it would “continue”.
The second amendment expands the provision to make clear that the OWTU’s status applies not only to collective agreements inherited from Petrotrin, but also “for the purposes of collective bargaining” going forward.
Opposition Senators objected to the changes, arguing that the amendments extended beyond clarification and could affect the rights of other trade unions.
Opposition Senator Faris Al-Rawi argued that the Industrial Relations Act already provides a process for determining recognised majority union status based on worker support, and warned that Parliament should exercise caution when legislating in a manner that could affect constitutional rights.
However, the amendment that generated the most extensive debate was the insertion of the words “and for the purposes of collective bargaining” into the legislation.
Independent Senator Michael de la Bastide told the Senate that the effect of those words significantly broadened the provision beyond what had originally been approved by the Upper House in June.
He said the original version of the legislation only recognised the OWTU for a limited purpose, namely the administration of collective agreements that had been entered into by Petrotrin before the appointed date.
“The OWTU is not deemed to be the recognised majority union for Heritage and Paria workers generally speaking,” de la Bastide said.
Instead, he said the union’s status was confined to collective agreements inherited from Petrotrin.
He argued that the addition of the new wording fundamentally changed the scope of the legislation.
“The effect of those words is to deem the OWTU to be the recognised majority union for Paria and Heritage workers not only for the purposes of past collective agreements entered into by Petrotrin but for the purpose of all collective bargaining generally, so going forward as well,” de la Bastide explained.
He contended that the amendment effectively grants the OWTU the same status it would have obtained if it had been formally certified by the Registration, Recognition and Certification Board as the recognised majority union for workers at the two state companies.
“The effect of those words that are now being added is essentially to confer on the OWTU the same status it would have had if it had been certified by the board,” he said.
De la Bastide further argued that recognised majority union status carried significant consequences under the Industrial Relations Act because it gives a union exclusive authority to negotiate collectively on behalf of workers and to bind workers through collective agreements.
The independent senator also raised concerns that the amendment bypasses the established certification process under the Industrial Relations Act, which requires a union to demonstrate majority worker support.
“Under the Industrial Relations Act... the board must be satisfied that the union has on the relevant date more than 50 per cent of the workers comprised in that bargaining unit as members in good standing,” he said.
De la Bastide described this requirement as a “democratic element” within the legislation because it ensures that a union has the backing of a majority of workers before being granted exclusive bargaining authority.
