At the moment you tell employees that it's their responsibility to tell you about someone who's job hunting, you will create a culture of mistrust. |
But at the manager, low-level director or employee level, there's no responsibility. |
From a management perspective, if it surprises you that someone leaves, it's because you weren't in touch with them. |
If you think you'll curry favor, you are mistaken. The boss now knows what kind of character you have. |
It means doing that day-to-day boring management task of staying in touch with people. |
