This paper analyses the contribution of modern management and leadership to achieving excellent diversity practice at work. It considers the classical management concepts like planning, organising, leading, controlling and motivation to support the practice of diversity effectively. Based from the author’s experience and research, it is found out that diversity at work is a claimed statement while it is not practised according to the sound management principles. To better address diversity at work, managers are expected to incorporate diversity through all their practices and see how the concept is successfully incorporated at work. This research is non-exhaustive as management practices do differ from one organisation to the next, yet its importance must not be understated. Leadership and motivational theory along with contemporary management practice also plays a key role in achieving diversity in today’s organisation and this is also aligned with sound practice of diversity.
