The Tenure Track

He's been green and upbeat for 50 years. Kermit the Frog is about to collect his 50th anniversary watch from his bosses and celebrate with a 50-city global tour.

Yet few U.S. workers make it to 50th anniversary service marks anymore, and their average tenure with an employer is dropping, according to the Bureau of Labor Statistics.

In 1983, people ages 45 to 54 had spent an average 9.5 years with their current organization; last year, that fell to 7.7 years. The median tenure was four years.

The government figures that 6.6 million workers have spent 25 years or more at one employer. Most are men, and most are 50 or older.

Kermit debuted in the 1955 television comedy "Sam and Friends," began "Sesame Street" in 1969 and for decades was Muppets founder Jim Henson's personal puppet. His career spans movies, music and books.

According to the feds, those who want to mimic Kermit's longevity might want to try life as a manager, architect, police officer or librarian. But if you want to hop around in your job a lot, check out a career in food service or become a child care worker or beautician.
