This is excellent for this purpose. All the employees are set up as authors, so the only content they can edit is their own, and it emails admin when they make a change. Admin then selects the version to be published (usually the latest) and away they go!
The version plugin that comes with it is also great as it allows for the provision of rollback if you mess something up in an article.
I like it, simple, intuitive, and fills a big hole in core joomla.
Thank you! We will definitely try to improvise!
