How does wage indexing work?
The principle of wage indexing is simple: when the prices of goods and services exceed a certain threshold, most wages are automatically increased, in order to guarantee the maintenance of purchasing power despite inflation, which increased from 3.20 % in November to 3.16 % in December 2024, and the increase in the cost of living.
In our country, there is no unique rule with regard to the indexing of wages. It differs from one person to another depending on the rules established by more than 200 different sectors.
However, two groups are distinguished: those who depend on the pivot index and those who index at a fixed moment.

What is the pivot index?
Once exceeded, the pivot index triggers automatic wage indexing of 2 % for employees in the public service and people benefiting from social allowances (for example, pensions or disability allowances).
According to the plan office, this index should be exceeded twice in 2024: in March and October.
What are the roles of the Smool Health and Health Index?
The smoothed health index, which consists of an average of 4 months of the health index, is the reference index for wage indexing. In addition to this average principle, this index is also distinguished from the consumer price index by the fact that it excludes alcoholic drinks, tobacco and fuels.
