     A different sort of generation gap is developing in the workplace. Someone - specifically the father-

daughter team of Larry and Meagan Johnson - has figured out that on some American job sites, five

generations are working side by side.    

     In their new book about generations in the workplace the pair argue that while such an age difference

adds a lot of texture and a variety of life experiences, it can also bring tensions and conflicts.    

     The Johnsons are human-resource trainers and pubic speakers. Dad Larry is a former health-care

executive; daughter Meagan is a onetime high-level sales manager.    

     Here are the oldest and youngest of the five generations they identify:    

     They call the oldest group Traditionals, born before 1945. They were heavily influenced by the

lessons of the Great Depression and World War. They respect authority, set a high standard of

workmanship, and communicate easily and confidently. But they’re also stubbornly independent. They

want their opinions heard.    

     At the other extreme are what the Johnsons call Linksters, born after 1995 into today's more

complicated, multimedia world. They live and breathe technology and are often social activists.    

     You won't find many l5-year olds in the offices of large companies, except as volunteers, of course,

but quite old and quite young workers do come together in sales environments like bike shops and ice

cream stores.    

     The Johnsons, Larry and Meagan, represent a generation gap themselves in their work with jobsite

issues. The Johnsons' point is that as the average lifespan continues to rise and retirement dates get

delayed because of the tight economy, people of different generations are working side by side, more

often bringing with them very different ideas about company loyalty and work values.    

     The five generations are heavily influenced by quite different events, social trends, and the cultural

phenomena of their times. Their experiences shape their behavior and make it difficult, sometimes, for

managers to achieve a strong and efficient workplace.    

     Larry and Meagan Johnson discuss all this in greater detail in a new book, "Generations, Inc. : From

Boomers to Linksters - Managing the Friction Between Generations at Work, "published by Amacom

Press, which is available in all good bookstores from this Friday.
