RT Journal Article SR Electronic T1 Changing Stability in U.S. Employment Relationships JF Journal of Human Resources FD University of Wisconsin Press SP 35 OP 69 DO 10.3368/jhr.0821-11843 VO 59 IS 1 A1 Molloy, Raven A1 Smith, Christopher L. A1 Wozniak, Abigail YR 2024 UL http://jhr.uwpress.org/content/59/1/35.abstract AB We examine how the distribution of employment tenure has changed over time. The fraction of workers with short tenure (less than one year) has fallen since the mid-1990s, a trend associated with fewer workers cycling among briefly held jobs and an increase in perceived job security among short-tenure workers. Meanwhile, the fraction of men with long tenure (20 years or more) has declined markedly, partly due to the secular shift away from the manufacturing sector and the decline in unionization, as well as an increase in mid-career separations during the 1970s and 1980s that reduced the likelihood of reaching long tenure.
