Which of the following was a result of german workers forming labor unions?

The german army and navy expanded in size

the communist party was established in germany

workers received health insurance and pensions

working conditions improved for the workers

The correct answer is:

Working conditions improved for the workers.

Before German Revolutions of 1848, the working conditions were very poor pay, so workers were stimulated to form labor unions in Germany. Many of the workers were socialist and the socialist party gained momentum. As a result of the heavy losses faced by the owners, they agreed to the union's requests and improved the working conditions of the employees.
