I negotiated this year down to 36 hours, being 4 days of 9 hours and Wednesdays off. It’s amazing. How to do it? I think it’s one of those things you can target on purpose. Regarding my case, I have a good relationship with my superiors, I fulfill the goals which are put in front of me, team is happy etc, etc.
