First, in nearly everywhere that ha

First, in nearly everywhere that has data available, part-time jobs pay less per hour than full-time ones. Sometimes this is within an occupation. A recruitment firm, Indeed, found that the hourly-pay penalty for part-timers in America was highest in jobs that rewarded strong client relationships, such as in retail, or where workers are always on-call, such as web development. But more often it is between occupations: the types of jobs that can readily be done part-time, or are offered part-time, are lower-paid than those that are not.
