Thesis working title

Antecedents and consequences of employee silence

This study aims to observe the causes and effects of employee silence in two different sectors, health and manufacturing, in two different countries, Australia and Thailand. Through the implementation of a mixed methods approach, it aims to increase the understanding of employee silence in different contexts, as well as connecting its antecedents to its consequences. It aims to contribute to improving managerial practices that organisations can apply, in providing their employees with more suitable workplace communication systems. This would in turn benefit them, for example, in terms of productivity, errors, employee well-being and job satisfaction.
