This study delves into the impact of knowledge sharing on innovative work behaviour within higher education institutions in Ghana, utilising data gathered from 285 participants. Employing a quantitative approach and utilising a descriptive-correlational research design, this research reveals a consistently high level of innovative work behaviour. All dimensions of innovative work behaviour, including idea promotion, idea generation, and idea implementation, received notably high scores. Likewise, the sub-components of knowledge sharing, namely the community of practice, organisational communication, personal interaction, and written contribution, were rated as high within these institutions. The study establishes a significant positive correlation between knowledge sharing and innovative work behaviour ([beta] = 0.88, p = 0.00). The study advocates for promoting knowledge-sharing mechanisms within higher education institutions, fostering an environment that facilitates seamless knowledge exchange amongst all members.
