The national collective agreement of October 31, 1951 (CCN51) sets the remuneration scale for private non-profit establishments in the health and social sector. For a nursing assistant, the base salary is only part of the actual remuneration: the increases related to night shifts, Sundays, and public holidays significantly alter the payslip depending on the work schedule.
Coefficient and point value: the CCN51 calculation basis
Before understanding the increases, one must master the mechanism that produces the gross base salary. The CCN51 is based on a system of coefficient multiplied by a point value. Each profession is assigned a reference coefficient, to which points related to seniority and, if applicable, functional supplements are added.

The gross monthly salary is calculated as follows: total coefficient x point value. This point value is revised by the social partners of the FEHAP branch. Any revaluation of this point automatically affects all employees covered by the agreement.
For a nursing assistant, the starting coefficient evolves with seniority. The transition from one level to another follows a predefined grid, without individual negotiation. A detail often read too quickly on payslips: the nursing assistant salary according to CCN51 also includes a seniority bonus distinct from the point supplement, which sometimes creates confusion between the two lines.

Night work compensation in CCN51: time frame and calculation method
The CCN51 defines night work as generally occurring between 9 PM and 6 AM. Any hour worked within this interval entitles the employee to a specific compensation for constraints, separate from the base salary.
The calculation does not function as a simple percentage increase of the hourly rate. The agreement provides for a flat-rate compensation per night worked, the amount of which depends on the point value and a defined number of points specified by the applicable amendment. This mechanism makes direct comparison with the public hospital sector (which operates on a flat hourly compensation) challenging.
What the payslip must mention
The night compensation appears on a separate line from the base salary. It does not overlap with the seniority bonus or any potential overtime. Checking for its presence on the payslip is the first reflex to have, as a night worked without dedicated compensation constitutes an anomaly.
Sunday and public holiday increases: two regimes to distinguish
Sunday work and work on a public holiday do not fall under the same system in CCN51, even though both generate financial compensation.
- Working on a Sunday results in compensation calculated in points, following the same logic as night compensation. The number of points assigned per Sunday is set by the agreement, with no room for negotiation for the employer.
- Working on a public holiday (excluding May 1) entitles the employee to a public holiday compensation or, in some cases, compensatory time off. The choice between compensation and recovery depends on the internal organization of the establishment, but the agreement regulates both options.
- May 1 follows a specific legal regime: if worked, the increase is mandatory, regardless of the collective agreement. The CCN51 cannot deviate from this rule to the detriment of the employee.
A point often misunderstood: when a public holiday falls on a Sunday, the two compensations do not automatically accumulate. The agreement provides for non-cumulative rules that must be read carefully in the amendment applicable to the nursing assistant profession.
Combining night, Sunday, and holiday: combinations that change the pay
Can a nursing assistant working the night of a public holiday Sunday accumulate all compensations? The answer depends on the precise reading of the CCN51 and any potential company agreements.
In practice, the combination of night + Sunday is generally accepted. The two compensations pertain to different constraints (night hours on one side, day of the week on the other) and add up on the payslip.
The combination of night + public holiday follows the same logic. However, the combination of Sunday + public holiday is the one that poses the most interpretation difficulties. Some establishments apply a non-cumulative principle, paying only the most favorable compensation. Others, under more advantageous internal agreements, grant both.
Check your payslip in three points
- Identify each compensation line separately: night, Sunday, holiday. A single line “global constraint bonus” hides the details and prevents any control.
- Count the number of nights, Sundays, and public holidays worked in the month and check the correspondence with the signed schedule.
- Compare the unit amount of each compensation with the current point value multiplied by the number of points provided by the agreement.
Wage gap between strict day and atypical hours in CCN51
A nursing assistant who only works during the day, from Monday to Friday, receives only their base salary plus the seniority bonus. Their colleague in a rotating position including nights, weekends, and public holidays may see their monthly remuneration increase significantly due to the accumulation of compensations.
This difference explains why some night or weekend positions attract candidates despite the constraints on personal life. The gap between a day position and a night/weekend position mainly lies in the compensations, not in the base salary, which remains the same with equal coefficient and seniority.
The non-profit private sector under CCN51 is positioned between the public hospital service (whose salary scales and bonuses follow a different regulatory framework) and the for-profit private sector (where the applicable agreement may differ, such as CCN66 or the private clinics’ CCN). Comparing salaries between these three sectors without considering the compensation for constraints skews the analysis.
Careful reading of one’s payslip, line by line, remains the most reliable method to verify that each night, each Sunday, and each public holiday worked has indeed been compensated according to the terms of the applicable agreement.
