It is easy to make companies cut your salary but difficult to make them respect the reduced work hours! Wife has been working nominally 4 days a week at the G of FAANG for several years. Prorated to 80% of the salary. Management has repeatedly stated that they expect far more than 40hrs/week from a full-timer, so an 80%-timer better turn in at least 40+ hours. Which largely defeats the intended benefit of doing a 4 days week.
