To what extent might a non-faculty staff member expect -- or demand -- academic freedom? Faculty and students are generally regarded as having some degree of academic freedom (tenured faculty sometimes having more than non-tenured). 

Non-faculty staff seem to be a different matter. Specific institutions might have policies addressing this, but I'm asking more from a general / philosophical standpoint: is there any basis upon which a non-faculty staff member at a university might expect -- or demand -- academic freedom? Or should non-faculty staff basically assume they do not have academic freedom?
The American Association of University Professors (AAUP) has a set of Recommended Institutional Regulations concerning Academic Freedom and Tenure, which has the following to say about academic freedom for staff:


Other Academic Staff

a. In no case will a member of the academic staff who is not otherwise protected by the preceding regulations that relate to dismissal proceedings be dismissed without having been provided with a statement of reasons and an opportunity to be heard before a duly constituted committee.21 (A dismissal is a termination before the end of the period of appointment.)
b. With respect to the nonreappointment of a member of such academic staff who establishes a prima facie case to the satisfaction of a duly constituted committee that considerations that violate academic freedom, or of governing poli­cies against improper discrimination as stated in Regulation 10, significantly contributed to the nonreappointment, the academic staff member will be given a statement of reasons by those responsible for the nonreappointment and an opportunity to be heard by the committee.
...
21 Each institution should define with particularity who are members of the academic staff.

Essentially:  those staff that an institution chooses to define as &quot;academic staff&quot; should be able to bring grievance against a &quot;duly constituted committee&quot; if they believe they have been terminated (or not reappointed) in retaliation for speech or actions that should be protected under the umbrella of academic freedom.
