When they make changes to content in the CMS, the changes are made to a branch on their fork. In the editorial workflow screen, they see only their own pending changes. Once they're ready to submit their changes, they can move the card into the "Ready To Review" column to create a pull request. When the pull request is merged (by a repository maintainer via the GitHub UI), Netlify CMS deletes the branch and removes the card from the user's editorial workflow screen. Open Authoring users cannot publish entries through the CMS.
