Our personalities are who we are – and we are very multifaceted and complex creatures. When managers and supervisors understand the personality of their team members, when they know what motivates them or rubs them the wrong way, and when they are able to put themselves in their employees’ shoes, everyday interactions become much smoother, friendlier and more productive. Personality tests also do marvels for team building, and make for a fun and insightful exercise, bringing team members closer and helping them to communicate better.
