Aalberse served on the municipal council of Leiden from September 1899 until September 1918, and served as an alderman in Leiden from September 1901 until February 1903. Aalberse became a member of the House of Representatives after the death of Herman Schaepman, serving from 24 February until 21 June 1916. Aalberse worked as a professor of Administrative law and Labour law at the Delft Institute of Technology from 21 June 1916 until 25 September 1918. After the 1918 general election, Aalberse was appointed as the first Minister of Labour in the first Ruijs de Beerenbrouck cabinet, taking office on 25 September 1918. After the 1922 general election Aalberse continued as Minister of Labour in the second Ruijs de Beerenbrouck cabinet, taking office on 18 September 1922. On 1 January 1923, the Ministry of Labour and the Ministry of Agriculture, Commerce and Industry were combined to form the Ministry of Labour, Commerce and Industry, with Aalberse continuing in the post as the newly renamed Minister of Labour, Commerce and Industry. After the 1925 general election, Aalberse was not given a cabinet post in the new cabinet, the Cabinet Ruijs de Beerenbrouck II was replaced by the Cabinet Colijn I on 4 August 1925. Aalberse subsequently returned to the House of Representatives as a frontbencher, taking office on 15 September 1925. After the leader of the Roman Catholic State Party and Parliamentary leader of the Roman Catholic State Party in the House of Representatives Willem Hubert Nolens announced his retirement from national politics, Charles Ruijs de Beerenbrouck was nominated as his successor as leader and Aalberse was selected as Parliamentary leader in the House of Representatives, taking office on 15 September 1931.

He gave up both positions in 1903, when he was elected into the House of Representatives for the constituency of Almelo. In the House, he was mainly concerned with policy regarding labour, trade and industry. After losing his seat in 1916, Aalberse briefly taught at the Delft University of Technology.
