Many information technology professionals are isolated within their own companies or work with a limited number of experts in their specific domains (Jenkins et al., 2020). This phenomenon, known as professional isolation, occurs when professionals have limited access to collaborative opportunities in the workplace (Kutoane et al., 2023). Professional isolation can negatively impact job performance and employee retention, contributing to a lack of employee confidence (Mannir et al., 2023; Spilker & Breaugh, 2021). Virtual communities of practice can transcend geographical, organizational, and temporal limitations, offering a potential solution for professional isolation (Mannir et al., 2023). A qualitative instrumental case study was used to explore the complex interactions and strategies employed by information technology professionals within virtual communities of practice. The use of an instrumental case study allowed for an in-depth description, exploration, and analysis of a bounded system--"a specific, complex, functioning thing" (Stake, 1995, p. 2). The findings of this study investigate the strategies utilized by information technology professionals on these platforms, as well as other interconnected phenomena, including professional isolation. The results of this study may be influential for information technology professionals, organizations, and educators.
