I'm a little rusty on the Workshop module as my recommendation to clients for quite some time has been to give this module a wide berth for anything that is remotely critical. You can see my concerns expressed in the discussion regarding a call for comments on a revised module (which sadly didn't emerge as a revision but a proliferation of modules).
A search in the Tracker will provide you with some insights into the current state of play.
I'd be happy to have a chat if you feel it would be beneficial. I'll drop you a message separately on this.
