Suggested tweak (to shorten it and tighten up the wording a bit):
Questions about company-specific regulations, agreements, or policies should be directed to your manager, your HR department, or an attorney. Questions that address only a specific company or position are of limited use to future visitors. See this postthis post for more information.
The linked meta post would, of course, be updated if we make this change.
This wording makes it clearer what the problem is, without producing false positives for the smaller set of law-related questions that actually are on-topic here.
