Why are CEOs not active on social media? It is increasingly critical for CEOs to not only be physically present at work but also be virtually present in the digital sphere. However, many CEOs are still reluctant to adapt social media or struggle to find the efficient approach to incorporate the tools into their communication strategy. The study explores how CEOs orient themselves in the digital world and make sense of social media. In particular, based on the view of impression management and institutional work, the research examines how CEOs translate their understanding into communication and selfpresentation strategies and activities. The results from 31 in-depth interviews with Chinese and Dutch CEOs suggest that leadership communication on social media is still going through the process of legitimisation in both institutions. Despite the growing popularity of personal branding, most CEOs do not interpret social media as the outlet for their personal and private use or independent from the organisational identities. While most CEOs champion the necessity of digital transformation for their organisations, they do not see clearly how their personal digital habits could potentially influence the process, despite their leadership roles. They typically identify social media as the functional platforms for information circulation and network connection. Multiple narratives and orientations do, however, coexist and they dictate social media decisions simultaneously depending on the context. There is also a prominent difference between the narratives of social media in the Netherlands and in China. Most Dutch CEOs wish active engagement from the organisations but practice passive roles themselves, while most Chinese CEOs are active for both personal and organisational use pressured by the intuitional norms. The research highlights the significance of cultural context regarding leadership communication even on social media. Given most platforms are designed, and arranged to have an international audience, CEOs and companies should be aware of distinctive norms and beliefs they are operated in the different societal institutions.

According to industry reports, a CEO’s strong social presence has a tremendous impact on the company’s reputation and their own image. However, despite being considered as digital influencers, most C-suite leaders fail to establish their own personal brand online. This under-development leads to the following questions: What are CEOs currently doing with their social media and why are CEOs (not) using social media? Interviewing 16 Dutch CEOs, this study explores the impact of the leadership style (transactional or transformational) and leaders' perception of narcissism in online impression management on CEOs’ social media activities. By investigating these relationships, the research further clarifies CEOs’ leadership communication strategies on social media and establishes the drivers and barriers for social media engagement to pave the ways for interested social CEOs. The results suggest that leadership styles may detect the content strategies and motivations of social media usage. The activity level, however, is determined by the perceptions of self-image and degree of a narcissistic impression on using social media. With this finding, we propose CEO social media activities can be typified into four categories: thought leader, storyteller, professional networker and selective performer. Transformational leaders tend to emphasize on being accessible and transparent to their audience. When they are positive about being narcissistic on social media, they are more likely to be a storyteller where they strive for charismatic and authentic content building. Conversely, a more reserved transformational leader would be a selective performer where they only publicize their stories in front of a selected group of audience, mostly through internal platforms. On the other hand, transactional leaders tend to focus on professionalism and efficiency in using social media. The ones who see the benefits of social media and are confident in sharing their own ideas tend to be thought leaders among their professional networks. On the contrary, the reserved transactional leaders rather using social media to connect with their professional network to obtain information than broadcasting their own voices. The study provides insights in how CEOs formulate their leadership communication online; further research should continue exploring the impact of various strategies on corporate performance and stakeholder engagement.
