Dr Kenneth Parku recently graduated with a PhD in Management Studies from the University of South Africa’s College of Economic and Management Sciences. His thesis, "Influence of Labour Relations on Organisational Performance of Selected Public Sector Institutions in Ghana", examines how collective bargaining, trade unionism and conflict resolution shape service delivery in Ghana.

Inspired by recurring strikes among nurses, teachers and university staff, Parku’s research found that while collective bargaining has a moderate positive impact, trade unionism often proves more disruptive than productive. He also identified under-resourced conflict resolution mechanisms, outdated legislation and a shortage of skilled labour relations professionals as key barriers to progress.

"These findings fill a critical gap in African scholarship," Parku says. "They challenge Western-centric industrial relations models that don’t reflect the realities of developing countries."

Conducting interviews during and after Covid-19 was among his biggest challenges. He adapted by using telephone and Zoom interviews, and narrowed his scope after some institutions declined to participate. Parku credits his mentors, Dr Elias Megbetor, Prof Frank Ohemeng, Prof Emelia Amoako Asiedu and Prof Theresa Obuobisa-Darko, for shaping his academic journey.

His doctoral studies were guided by his supervisor, Prof Thomas Buabeng Assan, and co-supervisor, Dr Elias Mochabo Moerane, Chair of the Department of Human Resource Management at Unisa’s College of Economic and Management Sciences. Parku praised their patience, dedication and commitment in bringing the thesis to fruition.

Now a 2026 PhD graduate with a Master of Philosophy in Human Resource Management and a BA in Business Studies, Parku plans to pursue an academic career focused on teaching, research and postgraduate supervision. He is currently developing journal articles on trade unionism, occupational health and safety, and performance management in Ghana’s public sector.

His advice to aspiring PhD students: "Choose a topic you are personally connected to. Contextualise your study for African settings rather than simply applying Western frameworks. And embrace your supervisor’s guidance – it’s invaluable."
