This study addresses the magnitude and impacts of Nonviolent Communication (NVC) in the expression of power in workplace relationships. It adopts the methods of surveys, group discussions and in-depth interviews with twenty practitioners from the civil society and across business sectors in Vietnam. Participants reported improved self-compassion, empathy, communication and collaboration with others after starting NVC practice. In terms of power expression, less harmful communication among participants and in peer-to-peer situations was employed, while the use of violent language toward participants could be minimised. The majority of participants have had more positive thoughts and behaviours to meet their needs (‘power-within’). They also tended to stop intimidating others (‘power-over’) to satisfy their own needs. Over half of the respondents shared stories about empowering others (‘power-to’) and collaboration with others (‘power-with’) in problem-solving (Kashtan 2002; Rosengbert 2015). Findings speak for a change in addressing legitimate power and hegemonic social norms and bias and show that people’s freedom in interactions among different relationships is reinforced, therefore it is crucial for international development to liberate the people from the power within which they struggle. In the context of global issues which require the collaboration between political, economic, and civil societies, NVC may initiate constructive social criticism. Ultimately, practising NVC is crucial for organisations to promote collective wisdom to meet the needs of individuals as a significant contributors through the organisations’ misions in fulfilling the planet’s needs. Finally, this research may expand its significance in the future by further investigating the impact of ‘expert power’ on the practicing NVC.
