Chick-fil-A, Zappos, Burton, Apple. These companies have an incredibly devoted employee base. Staffs are committed. Their businesses are successful. They've become legendary. Why?
One reason: a cult-like crazy culture. They are 110% in. To those outside of the organization, it may seem a bit weird or over the top. But to the employees working for these types of organizations, it is normal. They wholeheartedly believe in what they are doing, and it permeates throughout everything they do- their culture, their identity, branding, marketing, customer service, etc.
Simply put- it is part of who they are.
