Hiring in Argentina After the 2026 Labor Reform: 446 Collective Agreements Head to Renegotiation

On June 11, 2026, Argentina's Secretariat of Labor expanded from 150 to 446 the number of expired collective bargaining agreements (convenios colectivos) that employers and unions must renegotiate, implementing the Labor Modernization Law (Ley 27.802) through Decree 407/2026 (Infobae). For foreign companies that hire — or plan to hire — in Argentina, this is the most consequential labor development of 2026: the agreements that define working conditions in sector after sector are being reopened for the first time in decades.

The sourced, always-current entry for this measure lives on our regulatory radar.

What is "ultraactivity", and why does ending it matter?

Under Argentina's traditional regime, a collective agreement that expired never really expired — its clauses survived automatically until a new agreement replaced them. This "ultraactividad" froze working conditions negotiated decades ago (many agreements date from the 1970s–1990s) and removed any incentive to renegotiate.

The reform splits an expired agreement in two:

• Normative clauses — actual working conditions (hours, categories, tasks) — remain in force until renegotiated.
• Obligational clauses — solidarity dues and compulsory employer contributions to unions — lapse when the agreement expires.

That second point changes the bargaining table itself: the cost structure that made expired agreements comfortable for incumbents now has an expiry date, and both sides have a reason to sit down.

What exactly happens with the 446 agreements?

The 446 expired agreements — spanning industries from construction to services — enter a renegotiation procedure between employer chambers and unions covering two fronts: working conditions and solidarity dues / compulsory contributions. The Secretariat of Labor (Ministry of Human Capital) runs the procedure. The decree opens the door to renegotiating every clause that can be renegotiated within this process.

What it means for foreign employers

1. More predictable hiring costs — eventually, sector by sector

Modernized agreements mean job categories and conditions that match how work is actually done today, and an end to legacy contribution clauses an employer never negotiated. The transition is gradual: each sector renegotiates on its own timeline, so the practical picture depends on your collective agreement. Mapping which one applies to your activity is step one — it determines salary floors, categories and contributions before you make your first hire (see hiring employees in Argentina as a foreign company).

2. A window to enter while the framework modernizes

Argentina's labor law had been the most-cited deterrent for foreign employers. A framework being rewritten in favor of firm-level flexibility — together with the broader 2026 deregulation wave — shifts the calculus for setting up a local team now rather than later.

3. EOR first, entity when ready

If you want talent before navigating a renegotiating sector, an Employer of Record lets you hire compliantly while the new agreements settle, then migrate to your own entity.

Status and caveats

Decree 407/2026 is in force and the renegotiation procedure is underway — but renegotiations themselves will take time, and outcomes will differ by sector. Existing normative clauses remain binding until replaced. As always on these topics: this is regulatory information, not legal advice, and the status of each measure is tracked on our radar.
