The national collective agreement of March 15, 1966 (CCN 66) regulates the remuneration of employees in the social and medico-social sector according to a precise grid. The base salary results from a formula: coefficient multiplied by the value of the point. This mechanism leaves little room for free negotiation, but several levers exist to improve one’s remuneration without stepping outside the conventional framework.
Value of the point and Nexem gap: a quantifiable negotiation lever
Remuneration under convention 66 is based on an arithmetic calculation. In 2024, the value of the point is set at 3.93 euros for employers who follow the Nexem recommendation, compared to 3.82 euros for structures that do not apply it.
This gap may seem minimal on a point, but it multiplies by the coefficient of the position. For a specialized educator whose coefficient is around 400, the difference reaches several dozen euros gross per month. Over a year, the discrepancy becomes tangible.
During a recruitment or annual interview, asking what value of the point the employer is based on constitutes a first concrete argument. If the structure still applies the value at 3.82 euros, the request for alignment with the Nexem recommendation at 3.93 euros remains objective and does not fall outside the framework of the convention. The approach to negotiate one’s salary with convention 66 benefits from relying on this distinction, which is too often overlooked by the employees themselves.

Coefficient and seniority in convention 66: understanding one’s progression
The coefficient determines the positioning of the employee in the grid. It depends on the profession exercised, the level of qualification, and seniority. Each seniority level corresponds to a change in coefficient, thus an automatic revaluation of the gross salary.
The margin for maneuver lies at the time of hiring. The employer can recognize all or part of the previous experience to position the employee at a higher level. This mechanism, called seniority recognition, is not systematic in the same proportions from one structure to another.
Some associations recognize the entirety of the seniority acquired in the same type of position, while others only acknowledge two-thirds of it. Negotiation therefore focuses on the percentage of seniority recognized. Obtaining full recognition rather than partial can represent a difference of one or two levels right from the first payslip.
Preparing supporting documents before the interview
To support this request, it is necessary to gather previous work certificates and payslips. The employer needs formal proof to justify a higher positioning with their funders. Arriving with a complete file speeds up the decision and shows that the request is well thought out.
Bonuses and additional remuneration outside the base salary
The CCN 66 grid is not limited to the product of coefficient times the value of the point. Several supplements come into play, and their activation sometimes depends on an explicit request from the employee.
- The special duty allowance represents 9.21% of the gross salary for the majority of non-executive employees. It is normally applied automatically, but checking its presence on the payslip remains a reflex to have.
- The Ségur bonus, stemming from the Ségur health agreements, concerns a portion of the employees in the medico-social sector. Its amount and eligibility vary depending on the type of structure and funding. If the position qualifies, this bonus constitutes a significant addition.
- Night work, Sunday, and holiday allowances are added to the base salary according to the increases defined by the convention. A position with atypical hours can generate a net salary significantly higher than an identical position with standard hours.
During negotiations, not reasoning solely in terms of base salary allows for a broader discussion. An employer who cannot modify the coefficient may sometimes offer a position with conditions that qualify for specific bonuses.
Negotiation strategy adapted to the associative sector
The social and medico-social sector operates differently from the traditional private sector. The budgets of associations are often constrained by public funding (departmental councils, regional health agencies). The employer does not always have the latitude to grant remuneration higher than what the grid provides.
This budgetary reality does not close off all discussion, but it requires adapting one’s strategy. The arguments that work focus on elements that the employer can justify to their funders:
- The documented recognition of seniority through work certificates
- Alignment with the Nexem point value if the structure does not yet apply it
- The request for positioning in a higher coefficient job when the actual missions justify it
Requesting a “free” increase outside the grid is rarely possible within this conventional framework. The negotiation focuses on positioning within the grid, not outside of it.
The right moment to address the subject
At the time of hiring, the discussion is the most open. The initial positioning in the grid commits the entire career path within the structure. Once in position, the margins are reduced to changes in function or qualifications (obtaining a higher diploma, validation of acquired experience).
The mandatory professional interview every two years provides a formal framework to discuss a reclassification or a change in coefficient related to an evolution of missions. Preparing this interview with factual elements about the tasks actually performed gives weight to the request.

The CCN 66 structures remuneration in a seemingly rigid manner, but the combination of point value, seniority recognition, bonuses, and positioning in the grid offers several concrete entry points. Each of these levers should be prepared with documents and verifiable figures, which remains the best way to achieve a result in front of an employer who is also constrained by their funding.
