The NSF had an 100th Anniversary event on October 29th as start for the NSF Centennial. It was held in a wooden house in Grunerløkka in Oslo and it was very well attended. Greetings were held from IWA Secretariat (with seat in Poland) by the General Secretary, a comrade from SFManchester,
and a comrade from Ørestad LS, which is an IWA Friends organization. Later, it appeared 9 workers from a new grassroot initiative of transport workers from the big transport terminals in Oslo and surroundings, and they made a greeting to the NSF.
There were first speeches about the founding of NSF on December 28th of 1916 and the numerous direct actions the following years. The NSF was also in the forefront of making actions by taking the 8th hour day, and started to agitate for the 6th hour day as early as in 1919. A health worker/ historian , who is writing two books about the NSF, spoke about the development in Rjukan, a community where the NSF had 600 affiliates in 1920, and how the local branch of the main Confederation, the LO, sometimes cooperated, but most times undermined the NSF and its direct actions.
Another speech was about NSF activities in the twenties and thirties. The NSF joined the IWA at its founding Congress in 1922, and has since taken actively part in it. The NSF kept organizing in the twenties and thirties. They had also a women`s group that actively took part in the NSF
organizing efforts, and many of its members were also arrested during the World War II for illegal work against the Nazis.
