When is it acceptable to vanish from a job without warning or explanation, and why are more and more people doing it?

Ed Butler hears one woman give her reasons for doing just that, while web design entrepreneur Chris Yoko retells the tale of one no-show employee who took the art of ghosting to a whole new literal level. He also talks to the founders of the Japanese company Exit, which offers to provide resignation letters and phone calls for those too afraid to do it in person.

But why is ghosting - a cold shouldering tactic that first came to the fore in the online world of social media and online dating - becoming more commonplace in the real world of employment? Chris Gray of recruitment firm Manpower UK blames the booming jobs market, while Dawn Fay of US employment consultants Robert Half says whatever the reason, just don't do it!
