The paper focuses on the various forms of internal communication in libraries, which must take into account also the contract of employment (its duration, duties and wages). A correct communication should adjust knowhow and procedures, in order to reach organizational well-being. Moreover, the different contracts of the staff members should not impact on the quality of the services and therefore should not be perceived by users. The article offers an approach to staff training based on the analysis of library services, and establishes a relation between services and training required.
