Many famous leaders have changed the world: Nelson Mandela, Steve Jobs or Martin Luther King are only a few to name. Arete22, an outsourced event marketing specialist based in Liverpool, says: “Many have asked the question: What makes a great leader? Fact is that all great leaders have one thing in common; they come across as authentic.” Arete22 insists that businesses must understand the impact of leadership on their company’s success. In fact, research shows that 75 percent of people who leave their job voluntarily do not quit their job, but their boss. Great leadership has a positive impact on productivity, engagement and staff turnover. As a result, businesses that provide support and guidance to develop their leaders achieve a higher ROI and experience lower turnover rates.
