Senior agreement: when strategic workforce planning turns compliance into opportunity

39% of 60-64 year-olds are in employment in France. The law compels companies to act. SWP gives them a way to act well.

Since October 24, 2025, the employment of “experienced workers” has become a mandatory bargaining topic for companies with 300 or more employees. The legislator chose to extract this issue from the broader workforce management framework and make it a standalone negotiation, a clear signal that the matter deserves its own weight. The backdrop: an employment rate among 60-64 year-olds that tops out at 39% in France, against a European average of 51%. With longer working lives and pension reform reshaping the landscape, senior workforce management is no longer a peripheral concern.
But how do you avoid the “catalogue agreement” trap, a stack of generic, costly measures disconnected from the realities of the business? The real opportunity is to use this obligation as a lever to address senior workforce management in a targeted, pragmatic, and financially sustainable way.

What the law requires and what it leaves open

Three key points. Companies with 300 or more employees must negotiate a senior agreement every three years (or four, with a procedural agreement in place). Negotiations must cover four themes: recruitment, retention, end-of-career arrangements, and knowledge transfer. And a diagnostic assessment of the situation of experienced workers is mandatory before negotiations begin, failing to do so carries a financial penalty.
The law defines the “what,” not the “how.” The entire challenge is to make that diagnostic more than a statistical snapshot. It should serve as a steering tool, grounded in solid data, opening the door to constructive dialogue with employee representatives.
Bringing clarity to negotiations through strategic workforce planning
The mandatory diagnostic is a natural entry point for a Strategic Workforce Planning exercise focused on senior employees. The approach: don’t stop at counting seniors by job category. Add a forward-looking dimension to anticipate how those roles will evolve over time.
The parallel with broader workforce planning is direct. Just as robust negotiations are built on prospective analysis of jobs and skills, the senior agreement gains real traction when grounded in an objective view of how roles will evolve over a three-to-five-year horizon.
In practice, the approach starts with projecting the natural evolution of headcount: age pyramids by job family, projected retirements, natural attrition rates. This data quantifies the senior workforce challenge, role by role.
It then moves to business needs analysis, co-built with operational leaders. It is the business itself that assesses future headcount requirements, to execute strategy, absorb technological shifts, and respond to market dynamics. SWP is not an HR exercise conducted in isolation. It is a collaborative process that brings HR and business teams together around a shared view of workforce evolution.
Crossing these two dimensions produces a segmentation of senior-occupied roles into three categories: stable roles, growing roles, and roles where projected decline outpaces natural attrition. Because it is data-driven and validated by the business, this segmentation provides an objective foundation for shaping the negotiation.
The shift is from a descriptive diagnostic to a decision-enabling one.

Three situations, three families of measures

This is the heart of the approach: a tailored set of support measures matched to each situation.

Stable roles: securing the ability to stay in the job. When a role is expected to remain, the priority is not to organize a gradual exit, it is to sustainably preserve experienced workers’ ability to perform. The response must address the concrete conditions that make work viable over time: reducing wear factors, adapting certain organizational constraints, anticipating fragility before it translates into unwanted departures or absenteeism. The reinforced career review conducted before age 60 can serve as a useful anchor for surfacing these needs and triggering targeted adjustments, on ergonomics, working hours, or the scope of responsibilities, where needed.

Growing roles: organizing continuity of expertise. When a role is expanding, the challenge is not simply to retain senior employees a few more years. It is, above all, to secure the organization’s growing capability. The core risk is losing critical expertise at precisely the moment the business needs it most. The response is to make knowledge transfer a structured, recognized, and managed mission, adjusting workloads, embedding it in individual objectives, and, where needed, equipping experienced employees to teach what they know.

Roles where projected decline outpaces natural attrition: enabling a managed transition. When a role shrinks faster than natural departures can absorb, the nature of the challenge shifts. The goal is not to artificially preserve every existing situation, but to structure end-of-career pathways that are both socially responsible and economically sustainable. The response must serve three objectives at once: secure individual trajectories, progressively reduce surplus headcount in affected roles, and avoid abrupt disruptions. This is the context in which mechanisms like phased part-time arrangements, progressive retirement, or pro bono skills programs find their full purpose, not as generic entitlements, but as targeted transition tools.

The decisive argument: targeting makes the social investment sustainable. This is precisely where the approach changes in nature. Targeting does not mean reserving certain measures for a population as a matter of principle, it means aligning the right tools with the trajectory of the role the senior employee occupies: retention when the role is stable, transfer when it is growing, transition when it is declining faster than natural turnover can handle. The company concentrates its social investment where it matters most, for employees, and for the business. That is what makes even costly measures negotiable: they are no longer conceived as generic entitlements, but as targeted investments serving an identified, objective need.

A renewed social dialogue

Beyond the measures themselves, SWP changes the nature of the conversation.
By grounding discussions in a shared diagnostic, the debate shifts from ideology to strategy. Employee representatives can then participate in building the response, not from a pre-packaged plan, but from objective, legible trade-offs.
For CHROs, the benefit is twofold: an agreement that is genuinely useful, anchored in a real business need, and a smoother negotiation built on data rather than posturing.

In closing

The October 24, 2025 legislation creates the obligation to negotiate. Strategic workforce planning provides the method to turn that obligation into an opportunity. By combining workforce prospective analysis with demographic data, it enables companies to build a senior agreement genuinely rooted in business reality. By targeting measures to the trajectory of each role, companies contain costs and concentrate their social investment where it creates the most value. More broadly, this approach illustrates what social dialogue can become when it is built on rigorous analysis and co-constructed with the business: a pragmatic, clear-headed decision space, in the service of the company and its people.
