There is no work-around. We can share the media in the Shared iCloud Photos Library, but not the structure of the library. Each of us has to recreate the albums in our own library. It is the same limitation we are facing, when importing one library into another library. We are getting the photos and videos, but not the albums and folders.
This is probably meant to avoid conflicting album names and folder names. We are seeing the shared photos and videos as a part of our own library, and it could easily become a complete mess, if five different people are starting to share albums, all with the same name. Either we would have many duplicate album names, or our own albums with the same names would become messed up with photos we do not want inside our albums.
What I have done, is to use mainly smart albums based on keywords. And added to name of the album as a keyword to each shared photo. Then the other subscribers can just create their own smart album with the rule "keyword is " and they will automatically see the photos and videos in the correct albums.
