Due to the correlation between the organizational success and HR practices, globalization, and the drastic increase in the number of multinational companies (MNCs), it is beneficial to study the field of International Human Resource Management (IHRM). This research studies organizational HR in Croatian MNCs, as exploring unique development path, current status, and evolving future of the organizational HRs in Croatian MNCs could contribute with new insights for the IHRM field. Looking to provide those insights, this study aimed to respond to the following question: “How do HR employees in Croatian MNCs understand their roles, and what challenges do they face in this industry?” To achieve the aims of the study, data was gathered using in-depth interviews and analysed by applying a grounded theory approach. It emerged that HR employees understand organizational HR’s roles as a bridge through which employees’ needs and management priorities are aligned and organizational goals are achieved, for which they recognize the importance of open communication. The three challenges that emerged were managing workplace communication, talent acquisition and retention, and cultivating a positive organizational culture. The challenges are considered a direct consequence of HR employees not being able to fulfil their roles due to a lack of communication. In addition, it became visible that HR employees perceive that organizational communication changes organizational culture, reinforcing the importance of open communication. Future research should focus on exploring the role of open communication regarding the organizational HR.
