X Unide Collective Agreement 2026: what changes for companies and workers in the group

Key data

All companies integrated in the Unide group have had a new obligation since May 1, 2026: to adapt their contracts and internal policies to the X Collective Agreement of the group, registered and published by the General Labor Directorate through a resolution of April 20, 2026 (BOE-A-2026-9504). Its publication in the BOE gives it general and binding effectiveness against third parties, which means it is neither optional nor negotiable at the individual level.

This group agreement represents centralized collective bargaining that unifies conditions across all Unide group companies. Any contract or internal policy that contradicts what was agreed will be superseded by the agreement.

What does this regulation establish?

The X Collective Agreement of the Unide group comprehensively regulates labor relations within the group. The matters it covers are:

As it is a group agreement, bargaining is centralized: a single negotiating table negotiates for all Unide group companies, which prevents dispersion of conditions between companies but also means that no company in the group can apply conditions lower than those agreed.

Publication in the BOE gives it general and binding effectiveness against third parties, which means its compliance is enforceable even against those who did not participate in the negotiation.

Economic and operational impact

The entry into force of a new group collective agreement has direct consequences on the structure of labor costs and human resources operations in all Unide group companies:

• Salary costs: The new salary tables and economic conditions agreed upon may result in increases in the total wage bill if they improve previous conditions.
• Working hours and work organization: Any change in the agreed working hours requires reviewing shifts, schedules and time tracking systems.
• Professional categories: The new classification may affect job assignments, allowances and internal promotions.
• Contract adaptation: Existing contracts containing conditions lower than those in the agreement are automatically improved by it, which can generate unforeseen additional costs in the budget.
• Immediate enforceability: Workers can demand compliance with improvements from the effective date, which creates a risk of claims if the company does not adapt its conditions in time.

Since the agreement is group-wide, the impact is multiplied by the number of companies integrated in Unide: all must align simultaneously, which requires centralized HR coordination and labor advisory support.

Who does it affect?

• Companies integrated in the Unide group: All group companies are obligated to apply the agreement without exception.
• Unide group workers: All employees subject to the scope of the agreement can demand its compliance from the effective date.
• HR and labor relations departments: Responsible for adapting contracts, payroll, schedules and internal policies.
• CFOs and financial directors: Must review the impact on total wages and personnel budget.
• External labor advisors: Who provide services to any of the group companies must be aware of the new applicable framework.

Practical example

One of the companies integrated in the Unide group has workers on its payroll with contracts signed under the previous IX Agreement. With the publication of the X Agreement in the BOE on May 1, 2026, that company must review whether the salary tables, agreed working hours and professional categories of its current contracts are equal to or better than the new agreement conditions.

If any worker receives a salary lower than what the new salary table of the X Agreement establishes, they have the right to claim the difference from the effective date. The company cannot argue that the individual contract agreed on a lower amount: the collective agreement prevails over the individual contract in everything that is more favorable to the worker.

This process must be carried out for each group company simultaneously, making centralized and coordinated review from the group's HR area essential.

What should companies do now?

1. Obtain the full text of the X Agreement: Download it from the official BOE to know the exact effective date and all agreed conditions.
2. Review salary tables and professional categories: Compare the new conditions with current contracts and payroll of each group company to identify differences.
3. Adapt contracts and internal policies: Update any contract, agreement or internal policy that falls below the conditions of the new agreement.
4. Review schedules and working hours: Verify that the working hours applied in each group company comply with what was agreed in the agreement.
5. Coordinate with labor advisory: Given the group scope, it is advisable to have specialized advice to ensure correct application in all companies simultaneously.
6. Inform workers: Communicate internally the changes that affect them, especially regarding compensation and working hours, to avoid conflicts and claims.
