In the 1920s she first worked at the Institute of Red Professors and later at the Soviet Institute of Philosophy. Her appointment to lecture in philosophy at Sverdlov University,[citation needed] in 1921, was originally blocked by the Orgburo, but when Lenin was consulted he said that it should be allowed, on condition that she was kept under observation in case she started promoting Menshevism.
