I want the names of corporations/organizations that ALLOW the use
of christian faith principles in the provision of employee
assistance/family assistance  counseling to their employees. Regions of
interest US, Canada and UK.

There are a number of them... one that comes to mind is Tyson... as
well, for your research take a look at a couple of websites...
Marketplace Ministries and Corporate Chaplains of America. Both of
these companies have their client lists on their website and may be a
starting point for your research.

Hope this helps...
