I suspect that the difference is a lot of managers end up so overcommitted that they can't handle 1:1s with all their direct reports.
Of course, that's its own problem, but particularly in places where it's hard to get headcount, the management structures get wider and wider...
Mine is bi-weekly but my boss cancels it every time.
Yea I do weekly 1:1s with all my directs and have done so for the past ~13 years. Pretty standard.
Mostly I had team calls. Theoretically had 1:1s with one former manager but with both of our travel schedules it ended up monthly at best.
It's supposed to be bi-weekly here. But according to HR "that's not policy, just recommended". I had about 5-6 months were I only got 2 1-on-1s, and the feedback then was good. They completely dropped the ball and blamed it on the disabled guy.
