Employee engagement involves employees being committed to and involved in their organization and its values. There are three levels of engagement: actively engaged employees who strive to meet and exceed expectations; not engaged employees who focus more on tasks than goals and may feel overlooked; and actively disengaged employees who are unhappy and sow negativity. High employee engagement leads to lower attrition and costs, higher productivity and innovation, while disengaged employees undermine performance and productivity, hurt coworkers and customers, and can negatively impact their personal lives.
