Email, texting and social media have become perhaps the most popular forms of communication in many parts of the world. However, many people express themselves via these outlets in ways they would never do over the phone or speaking face-to-face. Many people using these vehicles of communication are curt, disrespectful, vulgar, etc., especially if they believe they can be so in anonymity. However, the writers come off as rude, unprofessional, petty, ignorant, inhumane, etc.
In an organizational setting, disrespectful emails can ultimately destroy morale and even bring down the entire organization.
