Okay, here’s some unsolicited advice from an IT manager. Please take with a heap of salt.

25 hours is too many for 1:1 weekly meetings unless that’s your whole job description. That leaves 15 hours for overhead, project management, team meetings, leadership meetings, scrum-of-scrums, town halls, mentorship, breaking ties on MRs, etc. At that scale, and assuming you have other responsibilities, 1:1’s really should be monthly, optional 3/4 of the time, or cut back to 15 minutes unless there’s an ask for more time. Also: ya gotta delegate those plan reviews if you can. With a labor pool that size, you probably have at least a few seniors or principals that can take it on.

Also, with 25 direct reports you’re practically a Director without any supporting management under you. It’s entirely possible that you’re being underpaid, especially if this arrangement pushes you into overtime (more than 40hrs a week) a lot.
