I started skipping most weekly 1:1 with my managers. But I wound up being there for a decade and we started blowing them off probably after I'd been there 4 years and was effectively the team lead, and didn't really want or need career help. Given that my managers, particularly the last one were all overworked that kind of worked out for them as well. Every now and then we had them but it was typically around raises and stock options and things like that, with the very occasional one around higher level project strategy and deliverables. The retros we had were usually where everyone complained about staffing, and I didn't really need a weekly 1:1 to complain about it more.
