The role of the "contact employees" became an element of differentiation. The important place granted to relational Marketing in the sector of the services does not cease evolving.

A review of literature has built a model studying, on the one hand, the impact of internalmarketing on attitudes and behaviors of service employees and, on the other hand, on the customer satisfaction in services companies. The results obtained show that Internal Marketing has an impact on the satisfaction of the two populations. The role of job satisfaction appears to be a mediating variable in the relationship internal marketing-customer satisfaction.
