Saint-Gobain Glassware Collective Agreement 2026-2030: Key Points for HR and Management

Key data

Saint-Gobain Glassware, SL has a new labor framework for the next five years. The agreement, signed on 23 April 2026 and published in the BOE on 23 July 2026, enters into force with effect from 1 January 2026 and extends until 31 December 2030. It affects all the company's work centers in Spain.

For HR managers and company management, this agreement is not just a reference document: it defines how work is organized, how it is remunerated and what mechanisms exist to resolve conflicts. Understanding it well avoids costly mistakes.

What does this regulation establish?

The agreement structures labor relations at Saint-Gobain Glassware around five main pillars:

The Joint Commission for Interpretation and Conflict Resolution is a relevant procedural innovation: any disagreement about the application of the agreement must first go through this commission before going to court or using extrajudicial mechanisms. Skipping this step may invalidate subsequent actions.

Regarding ultra-activity, the agreement takes a restrictive position: if on 31 December 2030 there is no agreement to renew it, the previous agreement is not maintained in full, but only the salary amounts. This has direct implications for planning collective bargaining from 2029 onwards.

Economic and operational impact

The impact of this agreement translates into three concrete operational dimensions for the company:

• Remuneration stability until 2030: The system of professional groups and remuneration levels sets a predictable salary framework for the next five years. Personnel cost planning can be done with greater certainty.
• Organizational flexibility through functional mobility: By expressly recognizing functional mobility as a management tool, the company has room to reassign workers between functions or areas without the need for case-by-case negotiation, within the legal limits of the Workers' Statute.
• Risk in the post-2030 transition: The limited ultra-activity clause (only guaranteed salaries) creates a strong incentive to close the renewal before expiration. If negotiations are prolonged, the non-salary conditions of the agreement would be left without collective agreement coverage, creating legal and operational uncertainty.

The fact that the State Glass Agreement acts as supplementary law means that, in matters not regulated by this company agreement, the sectoral agreement is automatically applied. HR managers must know both texts to avoid gaps in daily management.

Who does it affect?

• Saint-Gobain Glassware, SL HR Department: daily agreement management, application of professional groups, remuneration levels and functional mobility.
• Management and CFO: personnel cost planning until 2030 and negotiation strategy for renewal.
• Legal managers and labor advisors: application of the Joint Commission procedure before any legal conflict.
• Workers at all centers in Spain: directly affected in remuneration, work organization and functional mobility. Executives "Management" and highly skilled employees who request voluntary exclusion are excluded.
• Union representatives: participants in the Joint Commission and in future renewal negotiations.

Practical example

Imagine a production worker at a Saint-Gobain Glassware center in Spain, classified in a specific professional group with their assigned remuneration level. The company needs to temporarily strengthen another work area due to a peak in activity.

Thanks to the functional mobility clause recognized in the agreement, management can reassign that worker to the new area without the need to negotiate a specific agreement, always within the limits of the same professional group and respecting the remuneration conditions of their level. If a disagreement arises about whether that reassignment is correct, the mandatory first step would be to go to the Joint Commission for Interpretation and Conflict Resolution, not to the labor courts. Only if the Commission does not resolve the conflict would the legal or extrajudicial route be opened.

This procedure, properly applied, saves time and legal costs for both parties.

What should companies do now?

1. Review the classification of all staff in the professional groups and remuneration levels established by the agreement, with effect from 1 January 2026.
2. Verify which employees are excluded: identify executives "Management" and highly skilled employees who have requested or may request voluntary exclusion.
3. Update internal conflict resolution procedures to include the mandatory step through the Joint Commission for Interpretation and Conflict Resolution before any legal or extrajudicial action.
4. Review functional mobility policies to align them with the framework set by the agreement and avoid applications that could be challenged.
5. Familiarize yourself with the State Glass Agreement as supplementary text, to cover matters not regulated by this company agreement.
6. Plan renewal negotiations in advance: given that ultra-activity only guarantees salaries from 1 January 2031, it is advisable to start the negotiation process before the expiration of 31 December 2030 to avoid a gap in non-salary conditions.
