But fine ... we'll work with your version of things. Suppose you ran a large enterprise and a subordinate you had hired to run one division of that enterprise "found it necessary to go public" in an effort to pressure you into doing what he felt was needed for that division (as opposed to the enterprise as a whole, which is your responsibility.) Would you immediately end all your deliberations and do what that subordinate demanded?
