Final answer:
The post-World War II labor shortage in the UK led to increased unemployment rates, labor militancy, and potential economic slumps.
Step-by-step explanation:
The post-World War II labor shortage in the UK led to several outcomes. First, there was an increase in unemployment rates due to the sudden influx of men and women into the labor force. Second, there was a rise in labor militancy and mass walkouts across the nation in 1919. Lastly, economists predicted that the labor shortage combined with the end of wartime production could lead to economic slumps similar to the latter years of the Great Depression.
