Melissa,
I just answered a question similar to this and the user had a reusable site workflow. Is your workflow on the library for the documents?
As for permissions, the users would need to have site permissions to the site where the documents are being copied to and at minimal edit permissions to the library where the documents will end up.
Thanks Eric!
This was a great tip!
I was able to solve my issue by doing the following:
In the "Copy to SharePoint" Action I used the Override Credentials feature so that when users run the workflow it will not fail since it will be run under my credentials.

Thats great and something to do... glad to help. Can you mark the answer as correct or helpful. There have been two more questions similar, so this is a hot topic .
I also have this problem and created an edit group with edit permission, but copy to sharepoint action still didn't copy the document. This user is able to go to the published site and update a document, so I am confused on why the action won't copy the document in the workflow. Also the workflow doesn't fail or give any errors you only know you document didn't copy to if you manually go and check.
