The article looks at how earnings stability has changed over time for men and women from 1995 to 2015. They found that earnings stability stayed about the same for men, with ups and downs related to the economy. Women's earnings stability improved over time, but didn't change during the Great Recession. People who didn't answer surveys, had less education, were minorities, or worked part-time had the most unstable earnings. However, these groups didn't have a big impact on overall earnings stability. Temporary changes in earnings stayed steady, but long-term changes increased for both men and women over the past 20 years.
