In a world of rapid change, sudden crises and widespread use of social networks, the need to focus on internal rather than exclusively to external marketing is evident more than ever. The most valuable resource in tourism and hospitality are the employees who are in direct interaction with each guest on a daily basis. The human factor is the core of service activities and can have a decisive impact on the image and performance of a hotel. This paper will discuss the concept of internal marketing and the application of its tools in achieving greater employee satisfaction in the food and beverage department of the hotel, and consequently its impact on greater customer satisfaction and hotel business. In this regard, the importance of service culture, ways of communication within the organization and the impact of management on the motivation and quality of employee engagement will be discussed. Further in the paper, the role of the food and beverage department to the hotel will be discussed and aspects of the organization and operations of this department will be explained. Furthermore, the results of the primary research will be presented in order to get a picture of how recognizable internal marketing is and how much it is applied in the daily operation of hotels in the Republic of Croatia. The survey was conducted through an online survey questionnaire during August 2021 and January 2022. This survey included both managers and employees of the food and beverage department in 4 and 5 star hotels and, accordingly, two surveys were conducted, in order to determine possible differences in their experience of the application of internal marketing tools. The results showed a relatively high level of employee satisfaction and the application of certain internal marketing tools on daily business of the hotel food and beverage department, but also identified areas for improvement of managerial activity to improve employee satisfaction and productivity.
