In an age of insecurity, what does it mean to have a stable, long-term career with a single employer? While prior research often portrays secure employment as a desirable means of navigating the precarious labor market, it remains unclear whether workers themselves share this perspective. Drawing on 126 interviews with white-collar workers in highly secure employment at large bureaucratic firms in Korea, I find that job security is devalued—these jobs are viewed not as a privilege but as an obstacle to embodying a “culture of enterprise” that idealizes self-responsibility, flexibility, and mobility. Interviewees highlighted the social risks and unease tied to staying in their secure jobs, citing the lack of “growth,” meaning the development of marketable skills and experiences that are portable across organizations. I term this fear and distress of failing to meet the prevailing cultural ideal of self-entrepreneurship stagnation anxiety. This led some to leave their jobs and pursue alternative careers better aligned with enterprise culture, while others stayed but struggled with feelings of inadequacy. Only a small minority rejected enterprise culture in favor of even more secure employment. I argue that stagnation anxiety captures the emerging labor market insecurities experienced by workers in today’s fast-changing economy.

Sejin Um is a sociologist of work and organizations, culture, and gender, with a regional focus on Korea. She is currently working on her first book manuscript, tentatively titled Good Job If You Can Leave It: The Career Dilemma of Korean Office Workers. The book draws on over 120 in-depth interviews with young, current and former white-collar employees of Korea’s conglomerate firms (chaebol) to examine the tensions that arise when organizational structures premised on stability and loyalty clash with the broader culture that prizes mobility and self-fulfillment. It shows that workers grapple with the fear of “falling behind,” or failing to meet the prevailing cultural ideal of self-entrepreneurship. The book develops the concept of “stagnation anxiety” to capture this subjective dimension of insecurity and further examines the different ways in which workers respond to it. These findings suggest that shifting cultural understandings of what constitutes a good career have created new dilemmas even for those in highly secure employment.
