The index of wages according to the national collective bargaining agreement measures the evolution of wages and salaries (per employee or per hour) determined by contractual provisions set by collective agreements; the indices are calculated with reference to the fixed employment structure of the base period (December 2015).
At the end of December 2021 the coverage rate (share of national collective agreements in force for the wage setting aspects) concerns 9% of employees – about 5.9 million – and 47.7% of the total amount of wages.
In December 2021 the hourly and the per employee indices both increased by 0.1 from the previous month.
Compared with December 2020 the hourly and the per employee indices respectively increased by 0.7% and 8%.
On average in 2021, the hourly earnings index grew by 0.6% and that per employee by 0.7% compared to 2020.
