In recent years, the term "ghosting" has been used to describe situations in which a friend or partner stops communicating with you without any notice or explanation. Because there's no warning, it takes a little time before you even realize that the relationship is over. Unfortunately for employers, ghosting can also occur in the employment context. For instance, after a lot of effort, you make an offer to a job candidate, they accept, and you schedule their first day of work. On the day they're supposed to start, they fail to show up. Sometimes ghosting can happen even before you make an offer. Or, it can happen when an employee who has been with you for a while simply stops showing up for work. Here are 10 guidelines to help you avoid workplace ghosting.
