Why are fallout 4 settlers not working?

Fallout 4 settlers may not be working due to several common issues. They might be assigned to a job but are unable to reach the workstation due to obstructions or a lack of resources. Additionally, if the settlement's happiness is low or there is insufficient food, water, or beds, settlers may refuse to work. Lastly, ensuring that settlers are properly assigned and not assigned to multiple tasks simultaneously can also resolve the issue.
