The geothermal electricity project was put on hold until 1921, after the war, and after years of social unrest ended with the arrival to power of
Benito Mussolini, of whom the Ginori Conti and Larderel families were big supporters. The first general campaign in favour of a strike at
Castelnuovo, near Larderello, broke out in 1915. After the war, in which his children and wife (a nurse) served, the first strike hit the various establishments in the Larderello S.p.A., except in Larderello itself: the resistance of the worker's union ran from 9 May to 9 June and continued sporadically until October 1920. Work then resumed, with 400 employees being laid off, and free health care and guaranteed
sick leave being stopped. Workers also now had to pay rent for their homes, were enrolled in the
National Fascist Party (PNF), and came under surveillance and guard by members of the same PNF. The area fell under
fascist influence from Larderello, until the creation of the tenth combat battalion on 16 October 1920, the first and only in the area until 1922. In October that year, the workers participated in the march on Rome. Tuscan fascists built local networks through the various sports clubs or other diversions already set up under the influence of the philanthropic Larderel and Ginori Conti. ==Later years==
