Mergers and acquisitions (M&As) frequently underperform, often due to communication challenges. While traditional approaches view communication as a tool for smooth integration, this article introduces Critical Discourse Analysis (CDA) as a vital theory for managers to understand the deeper, often hidden, ways communication functions in M&As. CDA reveals how language isn't just about conveying information but actively constructs organizational reality, shapes power relations, and influences employee perceptions and actions during the critical pre-merger phase. This article explains the core principles of CDA and demonstrates its application by analyzing how experienced M&A practitioners discursively frame concepts like "openness," "fairness," and "participation." These examples show how seemingly neutral communication strategies can subtly reinforce managerial control, manage employee anxiety through controlled narratives, and naturalize specific M&A rationales. For managers, understanding CDA offers profound value by fostering a critical awareness of their own and others' communicative practices. It equips them to identify manipulative discursive tactics, consider the ethical implications of their communication, and strive for more genuinely equitable and transparent engagement, ultimately leading to more reflective and potentially more successful organizational change processes.
