It’s probably safe to say that everyone has said things in a heated moment they later regretted. It could be during an argument with a significant other or while scolding a child, for example. Depending on how one looks at it, the stakes may be considerably higher when such outbursts occur in the workplace.
This is particularly true of angry emails sent to colleagues. Not only are angry emails easier for some to fire off than if they were delivering the same message face-to-face, emails also don’t go away. They’re stored on an email server indefinitely in black and white.
