After coming back to Poland, on 23 June 1920 Narutowicz became the Minister of Public Works in Władysław Grabski’s government. He held that post until 26 June 1922 (in four different subsequent cabinets: of Władysław Grabski, Wincenty Witos and the first and the second governments of Antoni Ponikowski). After becoming the Minister of Public Works, Narutowicz immediately started to work on the rebuilding of his country, using the experience acquired in Switzerland as a pioneer of electrification. He would soon go about reorganizing the reconstruction bureaucracy and reduce the number of employees fourfold over the course of two years, in that way greatly increasing its efficiency.
