In undertakings with at least five hundred employees, any trade union that is representative in the undertaking may appoint an additional trade union delegate if it has obtained one or more elected representatives in the college of blue-collar and white-collar workers at the Social and Economic Committee elections and if it has at least one elected representative in one of the other two colleges.
This additional delegate is appointed from among the candidates in the professional elections who received at least 10% of the votes cast in the first round of the most recent elections to the social and economic committee, regardless of the number of voters.
