The arrangement you are looking for is typically for people who have contributed to an organization for decades, have a lot of organizational knowledge, and are close to retiring. - working part-time primarily solves a problem for you, not the employer. - pay is not a linear function of time. your value drops when you aren’t available during working hours or skipping initiatives, etc. - you are signaling to the organization that you’re not really into their thing and to yourself that you are not willing to take risk on your own thing (Paul G writes about this). I would advocate for working hard full-time to capture your full value, and then take time off to do other things.
