Is there a way to not allow sync of products which have an active workflow?

Hi, I am using an activation script to create a workflow on every time a specific product attribute is changed. It creates a workflow and assigns to the correct user.But irrespective of the decision-approval/disapproval/no decision, the product can be synced and the changes are visible on the site.

How do I stop sync for product changes which are unapproved/no decision in the workflow?

Thanks!
