After the war Sławska-Lipczyńska, now retired completely from her stage work, devoted her energies to teaching, working at the fringes of the theatre world to create love and respect for the theatrical arts. As part of this she organised dance groups in community centres. In 1945 the frontiers of Polish had changed dramatically, with the eastern third of the country (including Lviv, where Sławska had been born) becoming part of the Soviet Union and the eastern third of Germany becoming part of Poland. The changes were accompanied by massive ethnic cleansing programmes of during 1944/46. In the north, Danzig, which since 1308 had functioned (not without recurring tensions) as a multi-cultural city, became Polish, and it was here that in 1950 Olga Sławska-Lipczyńska took a post as a teacher of classical dance at the Choreographic Academy (""Liceum Choreograficznym" ").
