Likewise, the continuing decline of middle-skill jobs, some of which could be replaced by part-time jobs, may raise the share of part-time jobs in overall employment.12 Despite these challenges in assessing where the share of those employed part time for economic reasons may settle in the long run, the sharp run-up in involuntary part-time employment during the recession and its slow decline thereafter suggest that cyclical factors are significant.
Private sector labor market flows provide additional indications of the strength of the labor market. For example, the quits rate has tended to be pro-cyclical, since more workers voluntarily quit their jobs when they are more confident about their ability to find new ones and when firms are competing more actively for new hires.
