The Disclosure Of Organizational Secrets By Employees, Danny Franklin

Graduate Theses and Dissertations

Organizational secrets enable firms to protect their unique stocks of knowledge, reduce the imitability of their capabilities and achieve sustained competitive advantages (Hannah, 2005). In today’s business environments, the loss of valuable proprietary organizational knowledge due to intentional employee disclosure represents a substantial threat to firm competitiveness. Anecdotal evidence suggests that firms in the United States lose more than $250 billion of intellectual property every year, with intentional employee disclosure accounting for a significant portion of these losses (Dandliker, 2012; Heffernan & Swartwood, 1993). Thus, understanding factors that influence such intentional secret disclosure is a key concern, especially in knowledge-intensive …
