What is the easiest way to tell what resources a settler is assigned to in Fallout 4? [duplicate]
Solution 1:
No, unfortunately there is no overview of what all of your settlers are doing. The only current method to see what a settler is assigned to is as mentioned in your question.

Solution 2:
As mentioned in the answer in the comment, hovering over settlers will highlight the resources they are assigned to.
Additionally, if you hover over a resource, you can check the information window. If the settler symbol in it is red and not green, there is no worker assigned to it and therefore, it won't do anything.
