Emotional intelligence (EQ or EI) was created by researchers Peter Salavoy and John Mayer. Developing EI in the workplace means acknowledging emotions are always present and using them intelligently. Good managers have high emotional intelligence, allowing them to handle adversity, cope with change, and react appropriately to others' emotions. Eight important EI competencies for managers are self-awareness, initiative, sound decision-making, empathy, communication, influence, adaptability, and self-management. Developing these skills through self-reflection helps managers navigate uncertainty and build effective relationships.
