What organisation would have an enamel badge which reads l union fait la force eendracht baart macht?

The enamel badge with the inscription "L'union fait la force" (French for "Unity makes strength") and "Eendracht baart macht" (Dutch for "Unity breeds strength") is associated with the Belgian national motto. This motto is often used by various organizations, but it is prominently linked to the Belgian state and its institutions, as well as groups that promote national unity and solidarity. The badge may also be found within contexts related to labor unions or civic organizations that emphasize collaboration and strength through unity.
