Negotiations on wages provide an opportunity for the parties to examine the following data at branch level at least once a year:
1° Economic trends, the employment situation in the branch, its development and the annual or multi-year forecasts drawn up, particularly with regard to fixed-term employment contracts and temporary work assignments;
2° Any preventive measures planned in the light of these forecasts;
3° Changes in average actual salaries by professional category and by gender, with regard, where applicable, to minimum hierarchical salaries.
The information required for negotiation is determined by regulation.
