["Sociological Forum, Volume 36, Issue 1, Page 51-69, March 2021. ", "\nDoes digital media empower or disempower workers? In existing studies on how information and communication technologies influence work, researchers investigate work–life boundaries and how workers use digital media to obtain more control. This article focuses on how digital media influences daily interpersonal interactions in the workplace: how does social media use influence workplace hierarchies and power dynamics? Based on 56 in‐depth interviews with WeChat users in Chinese workplaces, I find that lower‐ranked individuals were compelled to constantly express loyalty and appreciation, and publicly submit to their superordinates by clicking “like” or commenting on their WeChat posts. They also had to provide immediate and polite responses to their superordinates in WeChat group chats after work hours or to non‐work‐related issues. The distinctive features of online interaction—lack of physical interaction spaces, recordability of past conversations, and n‐adic nature of online disclosures—created an environment where past encounters were omnipresent and accessible, and placed workers under permanent observability. This social interaction environment leaves little room for forms of resistance and, in response, employees retreat into cynical performances of submission. This study finds that, under certain circumstances, WeChat use actually intensifies workplace hierarchies and power dynamics, thereby sharpening social inequality, rather than eliminating it.\n"]
