Marketing to young people can teach you valuable lessons about managing Millennials.

Which Wich, a quick casual sandwich concept has a very cool offer here in Colorado. If you take a picture of yourself and a Which Wich bag on top of one of Colorado’s 54 peaks that is 14,000 feet or higher and bring that picture into Which Wich, you get a free sandwich.

Now, in addition to being a very cool word-of-mouth marketing tactic (I heard about the plan from a couple of climbers on the top of Torrey’s Peak), I think that this could be a very effective model for managers looking to build relationships with their Generation Y employees.

Imagine that you put up an “Employee Achievement” bulletin board in back. Each period (week, month, quarter, etc.), your employees can bring in a picture of themselves accomplishing something impressive, and you can hook them up with something cool and post the picture.

Off hand, four things I would consider impressive:

• Climbing a mountain
• Swimming with a dolphin
• Accepting a scholarship
• Building a house for Habitat for Humanity

Now, not only are you celebrating what your employees do, you’re getting to know who they are. You’re learning about their interests, their hobbies, and their passions. You’ll be tapping into the same impulse that drives employees to post pictures on Facebook, and you don’t even need an internet connection to do it.

(I’ve seen something like this in the back of my local REI, and that’s a company that for 12 years running has been rated as one of Fortune’s 100 Best Companies to Work For.)

To really take it to the next level, once per period, snap and print a photo of an employee doing something awesome at work and put that on the Achievement Board to recognize their performance at work.

If you ask me, that beats the hell out of “Employee of the Month.”
