Internal marketing is a concept that emerged from the concerns of companies in maintaining a high standard of services. The fact that contact personnel interact directly with the customer in the moments of truth, makes it essential that companies are always able to fulfill the client`s needs. Thus, valuing the employees and using them as a vehicle to obtain strategic objectives is the main goal of internal marketing. In Brazil, case studies on this theme are rare and the little existing research shows that internal marketing is still in initial stage. The present research explores the literature on internal marketing, through analysis and criticism, and verifies how Brazilian companies address this theme, interpret it and implement it. The results suggest that internal marketing is a new concept, but one that is already generating cultural change. What is not mentioned in the literature, but demonstrated here, is that internal marketing should not be implemented uniformly throughout the whole company, because some areas, such as the support ones, need more attention within the internal marketing program.
