I didn't think I'd be praising Macy's this week, but this is fantastic (click here).
300 employee influencers out of their employee base is close to nothing, but don't worry about that right now. You are potentially a new Marketing Leader, and you need to acquire new customers at low-cost / no-cost. It costs Macy's nothing to have employees perform AWARENESS work on their behalf. And if the employee actually sells something, the employee gets a percentage of the order.
Tell me why you aren't already doing this? You constantly ask for low-cost / no-cost ideas. Well, here you have one. Tell me what stops you from doing this?
