Three out of 10 single mothers would like to work longer hours than they currently do but say they are hampered by childcare problems, the national statistics office CBS said on Wednesday.
Other workers with a small part-time job would also like to work longer hours, the CBS said.
Single mothers in particular are being targeted as part of the government’s efforts to get people of benefits and into paid employment.
Last month, the CBS said some 60% of Dutch women had a job of 12 hours a week or more, compared with 53% 10 years ago.
One in three women work between 20 and 35 hours a week, up from one in four 10 years ago. Around 18% of women work over 35 hours a week, a figure which has remained stable over the past 10 years.
Almost half of the women with a part-time job say they have chosen to work less because of household and family commitments.
