What changed and who it applies to
What changed
Hiring halls — "whatever their name or form of organisation", whether run by a union or by a provincial or municipal body — still exist and may propose to an employer that asks for it a list of workers available for temporary tasks, with the candidates' CVs. What changes is what comes next, and it is verbatim: "The employer may hire the person suggested and/or any other it chooses, and the request and/or assignment of personnel through the Hiring Halls may not be deemed exclusive or compulsory". And the paragraph that gives it force is the third, because a hiring hall's exclusivity is almost never written into a statute: "All legal rules are hereby repealed, as well as the obligations arising from usage and custom, that conflict with this section and/or impair, to any degree, the principle of freedom of contracting and of choice of personnel by any employer that so requests". verif Mar 6, 2026 ↗
In force
In force with the law, from 6 March 2026. Section 129 delegates nothing: it does not order any regulation, does not create a registry and sets no adaptation deadline. It is self-executing from that day. verif Mar 6, 2026 ↗
Who it applies to
To both sides of the same door, and both are worth stating. The law says that hiring halls, whether run by the union or by a provincial or municipal body, may propose candidates to the employer that asks for them and pass on their CVs, but that the employer may hire the suggested person or anyone else, with the list being neither exclusive nor mandatory; and it repeals the practices and customs that run against that freedom verif. To the contractor coming from outside the province: it can now field its own crew, and the union list becomes one source of candidates among others thesis. To the person on the list, waiting: being on the list has stopped being the only route for a company to take them on, but it has also stopped being a preference thesis. It is the change that shows most in a place where employment depends on a single site: Añelo, Vaca Muerta, construction, the assembly of a mine. There the hiring hall was not paperwork: it was the order of the queue thesis. verif Mar 6, 2026 ↗

Our reading
thesis This section matters more than its size suggests, and the reason is where it lands: the barrier it removed was not written into any statute, which is why no earlier reform could touch it. The hiring hall rested on custom, and section 129 names custom and repeals it. ⇒ For the outside supplier, the direct effect is on the price of a bid: labour stops being an unknown priced with a margin for it. For the local worker, the effect is that the contact channel changes owner — the union used to hold the CV; now the worker has to get it there. What could break this reading: exclusivity living in a collective agreement clause rather than in custom. The section repeals "legal rules" and "usage and custom", and does not name collective agreements; until a case settles it, that is an unanswered zone. thesis
Analyze this rule for my company
Where it lands, province by province1
Neuquén This is where it is most measurable: construction in Neuquén has a hiring hall with people signed up waiting for work, and the oil workers' union opens its own in windows with no public calendar. Stripping it of exclusivity changes who decides the order of that queue and opens the door to the contractor from another province that today prices labour with a margin for uncertainty. mixed cheaper to respond: investing takes time, held-back supply shows up at once thesis
