Career
Sara came from a family that was initially prosperous but became impoverished while she was young. She worked as a dressmaker in a tailor shop which she helped to organize into a union shop. The workshop she organized, where all workers were paid the same wage and worked the same hours, was used as an example of a democratic workplace by the Russian writer Nikolay Chernyshevsky in his novel What Is to Be Done?.

In 1918 Sara moved to Warsaw where she worked as a trade union official in the local garment worker"s union. Later, together with the Bundist Victor Alter she headed a one hundred thousand strong labor union which joined together Polish and Jewish workers, the Landrat.

In 1938 she was elected to the Warsaw City Council, together with sixteen other Bund members.
