During World War II, the US government took steps to prevent vital factory work stoppages by implementing measures like forcing businesses to join the war effort and banning strikes.
Explanation:
The US government ensured there were no vital factory work stoppages during World War II by:
- The government forced 200,000 businesses to join the war effort.
