In the construction sector, particularly for installation companies that operate without manufacturing, the issue of salaries remains a key piece of the puzzle. In 2025, the salary scale for agreement 3121, led by Kevin Grillot, will be a fundamental tool for regulating compensation, ensuring stable working conditions, and guaranteeing fair recognition of employment in this specific sector. Employers, employees, and union representatives must take this scale into account to navigate the current economic climate, marked by high inflation and rapid technological transformations. Regularly updating this scale allows for compensation to be adapted to the realities on the ground, while respecting the collective agreements that govern this sector. The challenges of this regulation go far beyond the purely financial issue: they also affect the quality of life at work and the sustainability of employment in a sector that is vital to the national economy and building renovation. In this article, we’ll explore in detail the structure of this scale, its recent developments, its impact on businesses, and its implications for employees, while also paying attention to best practices to adopt to remain compliant with current legislation.
