It's true that many…marketing channels are primarily geared toward reaching current and potential customers, but you should also endeavor to reach another very important constituency through your full-spectrum marketing efforts—your employees.

-Kirk Kazanjian, Driving Loyalty

It's no surprise that marketing is almost entirely focused on the acquisition and retention of customers; after all, they are what keep your business going.  But by that same token, your employees also keep your business going, and they are your internal customers.  As such, they benefit from marketing efforts just as much as your customers, just in a different way.  

It's clear that employee loyalty and employee turnover are related to how engaged and "connected" your employees feel to your company.  Many marketing channels, especially the newer social media and online options, are exceptional ways to reach your employees and build this connection.  For example, newsletters can be easy to implement and are a great opportunity for keeping employees up-to-date on your latest business news, as well as for recognizing individuals or departments who has performed well.  Social media, such as a Facebook page exclusively for employees, can go even further, as it also increases a feeling of live-time awareness of the company and fosters team building efforts and direct communication between employees even from different departments.  Whatever the best communication channels for your business, what's important to keep in mind is that your employee marketing should be all about reinforcing a positive company culture and strengthening engagement.
