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 (β = 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.
