If an author signed away exclusive publication rights to a publisher (i.e. the standard contract for non open Access journals), the author is no longer allowed to publish the content in another publication. If the author would like to use the content for a cumulative dissertation, i.e. publish a collection of published papers in bound form as their doctoral thesis, permission by the publisher is required for each text. How is your experience with this? Are publishers allowing this? Are they asking for additional conditions? Should authors consider his in advance when signing the original contract with the publishers?
