Millennials might have shorter attention spans, but they are apparently less interested in having fun at work than their parents' generation, according to a new report by Gallup.

Actually, the survey by the venerated pollster showed that American workers in general are unlikely to say that having a "fun place to work" is the top priority for them when seeking a job. Less than a quarter of millennials, Gen X-ers, and baby boomers said so, although millennials, who are now the largest group of workers in the U.S., were slightly less likely to say so than the other two groups.

Similarly, nobody appears particularly interested in having an informal workplace, or it is at the very least not a deal breaker. Less than quarter of members of all three generations said having a casual work environment was a top priority.
