Employers have had it good for way too long. Back in the old days, you would put together a written outline of the ideal candidate, compose the perfect job post and then wait for the resumes to roll in. Today, being ghosted by a new hire is a real risk.

You would then schedule interviews and make your selection based on your selected criteria.
Then you would move to the on-boarding phase and finally allow your employee to “own” their position.
Enter ghosting.
This new trend is rather karmic, and leaves employers scrambling to pick up the pieces after a new hire leaves without as much as a goodbye.
Getting Ghosted is stressful and affects your bottom line, but thankfully there are steps that you can take to decrease the chances of being ghosted by your employees.
The best protection against being ghosted is a good relationship from the first conversation. Stay in touch between the offer and the start date, be clear about what the role involves, and make the first few days welcoming. People rarely vanish from a place where they feel valued. If you want to look at hiring more broadly, have a read of how to attract and retain the right staff. For some general background, there is a helpful overview on Wikipedia.
