The overall pay gap between men and women decreased between 2020 and 2022. But the unexplained part of this difference continues to increase, according to the latest figures from the OFS.
Women earn on average 16.2% less than their male colleagues. This is what emerges from the analysis of salary data from the Swiss survey on salary structure, carried out by the Federal Statistical Office (FSO).
This salary gap is tending to decline little by little, since this share reached 18% in 2020 and 19% in 2018.
The unexplained part of the increasing gaps
The average salary of a man in Switzerland is 8,398 francs per month compared to 7,034 francs for a woman. How is this monthly difference of 1,364 francs per month explained, which reaches a total of 16,368 francs at the end of the year?

Objective elements, such as the level of training, seniority in the company or even hierarchical position, partly explain these disparities. But an ever-increasing part of this salary gap cannot be justified by a difference in profile, nor by the characteristics of the position occupied or by the field of activity. This unexplained disappearance of salary then becomes salary discrimination based on sex.

Big differences depending on the branches

Women active in retail are paid 17.4% less than their male counterparts, but almost 60% of this salary difference cannot be explained by objective elements. In the transport and warehousing sector, more than 89% of the wage gap between the two sexes has no justification.

Note that the higher the hierarchical level occupied within the company, the more the unexplained salary difference is reduced. In 2022, it represented 50.5% of the salary gap among senior executives (55.2% in 2020) and 82.8% for employees without a hierarchical function (81.8% in 2020).
