Since the beginning of history, we humans have found ever more effective ways of communicating with each other. Now e-mail, the fastest and most powerful communications tool ever, has arrived and with it a complex array of legal and interpersonal issues. Harassment has appeared on-line wearing a variety of disguises. Discrimination in employment issues are surfacing. Organizations are struggling with what is appropriate and inappropriate personal use of business e -mail. What (if any) privacy can we expect from this technology? What are the legal liability issues? Organizations and individual employees are facing litigation arising out of the illegal use of their e-mail systems. Messages that employees thought had been deleted are being discovered in back-up tapes and elsewhere by high tech detectives and used as evidence in lawsuits. Productivity that is supposed to be enhanced by the speed and power of e-mail is, in many organizations, being negatively impacted as employees use their e-mail for personal communication, to run their own private businesses, to send jokes (some of which are inappropriate or offensive) to their co-workers or to "flame" those they don't like.
