Implementation of the first LNS collective bargaining agreement
In 2023, the LNS Human Resources Service played a key role in the implementation of the first collective bargaining agreement at LNS, as well as in the drafting of new salary regulations specifically for medical specialists and pharmacist-biologists. The aim of this ambitious project was to structure and improve the working conditions of our private employees, by providing them with a clear and fair framework.
A major project carried out in several key stages
The first phase of the project involved finalising, together with staff representatives, the salary grids and classifying our functions. All employees were then individually repositioned on the new grid corresponding to their function. This process was carried out rigorously to ensure a smooth and equitable transition, guaranteeing each employee a minimum salary increase of 2%.
The second phase of the project involved recalculating the salaries of the 300 employees concerned over a period running from January to June 2023, enabling the new contractual remuneration to be applied retroactively. This operation resulted in the issue of 3,300 pay slips, reflecting the necessary adjustments. Transparent, individual communication with each employee enabled this stage to be completed smoothly and efficiently.
Finally, all the new benefits defined by the agreement were implemented, including meal vouchers, the one-off bonus, the responsibility bonus, holiday pay and additional days’ leave, and are finally reflected in new model employment contracts.
Thanks to rigorous teamwork and effective collaboration, we have succeeded in introducing better working conditions and a more structured working environment, with the ultimate aim of strengthening our corporate culture based on the well-being and motivation of our employees.


The completion of this major project was made possible by the determination and sustained efforts of the HR team. This collective success marks an important step in our commitment to offering fair and motivating working conditions to all our employees.
