What group of professionals based on generational age do you think is the most engaged in the workplace? If you guessed the very young and the older age groups, you were right. A recent survey by Quantam Workplace identified the most and least engaged groups in the workplace based on age. Among the most engaged were young Millennials under the age of 25 and Baby Boomers over the age of 66. The least engaged were older Millennials between the ages of 26 and 35 years old.
