A couple reasons to get the consent. First, the company the C works for requires it. Second, it is apparently a professional requirement.
I have been told that my W's C should not have seen the k's w/o my consent. In fact, it was not only against professional regulations, but may have also been ILLEGAL - could be consequences if I pushed the issue.
