"Dutch women's refusal to seek longer hours has long bewildered economists. In the spring, the United Nations, suspicious that there was something keeping women from full-time jobs, launched an inquiry to see whether the Netherlands was in compliance with the women's rights treaty. A comprehensive 2009 study by Alison L. Booth & Jan C. Van Ours looked at the amount of time women in the Netherlands spend at work compared with women in other European countries. The authors assumed that part-time work was less desirable but ultimately confirmed that Dutch women don't want to spend more time at work."
