Levels of work engagement do not vary by career stage or life stage, but they do vary by chronological age. Specifically, work engagement is greater among employees who are 50 and older (5.70 on our seven-point scale) and those between the ages of 40 and 49 (5.64) than it is among employees between the ages of 30 and 39 (5.43) and those who are younger than 30 (5.37).iii
