Leader vs. boss. Why are we still discussing this matter? That’s because we need leaders and not bosses. However, how can we differentiate between these two birds of a feather? Besides, when there is leadership in your organization and not bossship, you can see a 50% increase in employee retention rate and a 20% increase in productivity. However, if there are people of higher authority bossing around everyone, there will be a marginal decline in these and other stats, such as employee engagement.
