Massachusetts Mutual Life Insurance Company

Median Employee Age: 38

Median Tenure: 0.8 (Years)

Median Pay: $60,000

Rank: 1

The 93rd ranked firm in the Fortune 500 list (as of 2010), Massachusetts Mutual Life Insurance Company, has registered the least employee tenure among all the Fortune 500 companies. An average employee at the firm is expected to last only for 8 months and the possible reason behind this short stint is the high level of stress and pressure associated with the demand for huge turnovers.

Median Employee Age: 38

Median Tenure: 1.0 (Years)

Median Pay: $38,000

Rank: 2 (Tie)

This can be deemed as the major reason behind this short tenure of the employees.
