Hi Bhrath, thanks for your question. Although it would be great if all communications between suborodinates and a supervisor were documented, that is would be unrealistic in many circumstances and professional situations. In addition, since there is an "never ending" trail to emails, most supervisors would never ask their subordinate to do anything unethical in "writing." As we have read in many of the recent scandals and trials, emails can be key in trials. Therefore, people have become loathe, or at least stop and think twice for "memoralizing" any of their comments/requests in either emails or texts.
