Seven jobs in a lifetime? An analysis of employee tenure
分析了四组年轻工人（按性别和学历划分）的任职次数与期限，并与20年前出生的年长工人对比，发现年轻工人职业生涯头十年平均有至少七份工作，多数任期不超过一年。
Abstract This analysis examines the number of jobs and the lengths of employer‐specific tenures for four cohorts of relatively young workers: male and female high school and college graduates. It compares those measures with the experiences of an older cohort of workers who were born approximately 20 years earlier. Young workers today have many jobs—at least seven—over the first decade or two of their careers. The majority last no more than a year. Hazard models for the annual probability of separating from an employer show that short tenures are associated with a high probability of leaving.
