According to a new study by sociologists from Indiana University and Cornell University, one of the biggest contributing factors to the wage gap is the phenomenon of “overworking” – which means working 50 hours a week or more.
The study, using data collected by the US Census Bureau, found the relative hourly wage of overworkers compared with that of full-time workers had increased substantially over the past three decades, but because a greater percentage of male workers were overworking, this change benefited men much more than women. Today, women earn an estimated 81 per cent of what men are paid.
According to Youngjoo Cha, a sociologist at Indiana University who contributed to the study, even women who are employed full-time typically have more family obligations than men, which limit their capacity for putting in gruelling hours at the office.
