Previously maybe. The trend towards acquiring internal recruitment teams is growing dramatically. Despite not actively looking for work, I've had four job offers for internal recruitment roles in the last 6-8 months.
Remember that oftentimes by the time an employee comes to tell you he’s leaving it’s too late to retain him.
I have to disagree. It's difficult to convince an employee to stay when they inform you they want to leave and quite often it's not worthwhile as their motivation to leave will resurface again in a few months but it can and has been done successfully if you know how to go about it and actually listen and understand your employees needs.
