A preliminary investigation by the Secretariat of the Swiss Competition Commission into information exchanges in the Swiss labor market has found indications of collusion on employee compensation and benefits among more than 200 large companies in various sectors. While the preliminary investigation was initially limited to the banking sector, it became apparent that information exchanges on wage-related topics also occurred in other sectors. Due to the large number of parties involved, the Swiss authority decided that developing best-practice guidelines would be more effective in remedying the situation than launching an in-depth investigation into the behavior of each company. Therefore, the Swiss authority closed the preliminary investigation without opening a formal investigation and without imposing any sanctions.
