My standard workweek is 20-22 hours. I work 4 afternoons and an evening, with an occasional morning thrown in every week or three. I get a (mandatory, ha!) vacation of two weeks around Christmas/New Years and four weeks in summer. The four weeks are paid by my employer (as is the law in the Netherlands), any additional days off (Chrismas break, a week in fall, a week in spring, two weeks in may) depend on how much overtime I've worked during the year. I save up for my vacations by working unpaid overtime at a one-on-one basis as I see fit. As long as my time off matches school holidays, that is. That's the caveat, I can't take just a random day off during schoolyear.
What I've noticed regarding my thoughts and feelings about FIRE:
On a week-to-week basis I really like the relaxed vibe of parttime work and I am perfectly content with working a few hours a day. Ample time to get housework done, time for hobbies, time for visiting friends and relatives on our free days. Work feels like a slight interruption from life instead of the other way around. Obviously my pay is humble, but I really like the work-life balance of this arrangement. Having extra time grows on you very quickly!
FIRE is still luring at the horizon, more for the FI than the RE at the moment. Whenever kids come into our lives, I want both of us to have the freedom to scale work down to a level we think is needed or wanted. Luckily we are both in a country/field where this can easily be done, without it being as black and white as Full-time vs. Quit. That way a slightly less ginormous stash is needed for the future.
