As labour minister, Holt's foremost task was to prevent industrial disputes from disrupting the war effort. He met with union leaders and employer groups, and secured their agreement to a streamlining of the arbitration process while the war was underway. He had also been made Minister in charge of Scientific and Industrial Research, which gave him responsibility for the CSIR and its wartime efforts. In April 1941, Holt sponsored and oversaw the passage of the "Child Endowment Act", which introduced a universal child endowment scheme; newspapers labelled him "the godfather to a million Australian children". When leadership troubles hit the Coalition later in the year, Holt initially supported Menzies. However, he and five cabinet colleagues eventually transferred their allegiance to Arthur Fadden, the leader of the Country Party, believing this way the only to ensure stable government. Menzies felt he had been betrayed, but forgave Holt and accepted his assurances that he had been acting in the best interests of the country.
