The best rep on your team has a buddy who is an awesome and gainfully employed rep on another sales manager’s team. Before starting your search, it’s important to remember that your next great hire is A) employed, and B) is already thought of highly by their own manager. Basically, your next superstar is a super star for someone else right now.
What does that mean for you?
It means that it’s going to be hard to pry them away from their current place. They’re not looking because they are valued by their current company and performing well. That is only going to be dislodged by someone else, ie. your top performer; their friend. Utilize your own best reps to find your next stellar sales hire.
