As a manager, you never have an immediate need for regularly scheduled 1-1 meetings. You can always just ask your directs for their time and expect to get it -- rare is the employee who says no to a request from their manager to talk.

Regularly scheduled 1-1s are for the direct, to have a dedicated, planned 30 minutes a week to talk, with a person who controls your access to food, water shelter and all material needs, but whose calendar is often booked solid. Even when there's no immediate need for clarification, approval or discussion, theres still discussion about promotions and career development that need to happen more frequently than once a year or quarter.
