The Catholic Union of Government Peronnel (Dutch: Katholieke Bond van Overheidspersoneel, KABO) was a trade union representing blue collar public sector workers in the Netherlands. The union was founded in 1914, when the Roman Catholic Municipal Workers' Union, "St Paulus", was reconstituted as the Dutch Roman Catholic Bond of Government Staff, also known as "St Paul". In 1925, it was a founding affiliate of the Roman Catholic Workers' Federation, and in 1945 it joined its successor, the Catholic Workers' Movement. At this point, it had 13,110 members.
