Stack is designed for this workflow. It looks like you've done
everything right (but note that including the stack.yaml in the library
is only strictly necessary for building it independently).
On SO you list the error as
Failed to load interface for ‘Network.Worker’
Does your library list that package under 'exposed-modules' in its Cabal
file?
