Co-workers jokingly send an email around the workplace and it eventually gets to the manager.
Questions to ask learners: Has anyone ever mistakenly sent an email? Has anyone mistakenly hit "reply all?" Be careful of electronic communications as they are so quick and easy, they can get you into trouble quickly. They also create a record of everything said and can be used against you. Lastly, once you hit send, you have no control over how your comment is published to others.
