To what extent does employee loyalty and commitment to a brand drive overall customer loyalty? This research paper (.pdf) tackles that question and concludes that employee attitudes toward their company have a high degree of impact on customer loyalty. What the authors essentially argue is that fostering a corporate environment that espouses a unique and positive corporate culture grounded in clearly defined values goes a long way to inspire employees to be more engaged with their company and brand. Once this baseline is met, the authors propose that brands create internal employee engagement indexes to monitor employee sentiments toward the brand (similar in concept to consumer engagement metrics) to ensure they remain committed to the brand and ultimately the customer. Thus, the company can ensure that it’s employees are working towards increasing customer loyalty. A perfect example of this is Zappos.
