I guess my personal experience collaborates this: I started working 4 days a week for personal reasons, using a large chunk of saved vacation days (we in the Netherlands have quite more then in e.g. the US), and then just made that permanent. It helped that in that timeframe (end of previous century) more women were starting in IT, and parttime work was accepted. In my later years as a IT consultant in the public sector, several clients actually only hired for a maximum of 32 hours a week.
Now no longer working through an agency, I was kindly asked if I could work for longer hours and accepted, so now working 36 instead of 32 hours a week.
