The text on the poster translates to: "We solidify organization through labor. We always focus on quality... We declare every working day as a day of shock work!"
Shock work, or "udarnichestvo" in Russian, was a socialist labor phenomenon in the Soviet Union where workers voluntarily put in an extra effort, often exceeding their quotas, to demonstrate their dedication to the cause of building a communist society. It originated during the first five-year plan in the late 1920s and early 1930s, aiming to boost industrial and agricultural productivity. The government often incentivized this work with material and social rewards. The practice of shock work was glorified in the media, arts, and numerous propaganda materials, like the poster you're asking about.
