Differences in attitudes and behaviors, regularly exhibited between youth and their elders, are frequently referred to as the "generation gap". On the job, these generational distinctions are becoming increasingly complex as "multi-generation gaps" emerge, with three or more generations defining roles and expectations, each vying for positions in a work world of shrinking upward opportunity. Generations at work include at least four segmented population groups defined by common birth years or years entering the workforce. They include the Veterans (born 1929-1942), Baby Boomers (born 1943-1960), Generation X (born 1960-1980), and Generation Y (born 1980-2000). Recognizing and understanding the characteristics underlying each generational viewpoint can help managers decipher the unspoken assumptions beneath employee attitudes and actions.
