Some fairly standard advice here from Peter Yang on How to Run Meetings That Don’t Suck, but this point in particular is so important:

Try not to cancel or move 1-on-1s. If you’re a manager, it’s easy to move or cancel your 1-on-1s for other “important” meetings. This is disrespectful to your direct reports. Even if you see them everyday, nothing beats a private half-hour conversation where they can be open about real issues.

How we show up in meetings as leaders is very telling about how we view our team’s time. The most important rule is this: do not be late. I know this is hard to do in our culture of back-to-back meetings, but nothing says “I don’t respect your time” like consistently showing up 5 minutes late to meetings with no explanation. Here’s a quick tip: if you need a minute to go to the bathroom and/or get some more tea or whatever, make sure you join the meeting first and tell the person/people that you just got out of another meeting and you will be right back. Oh, and do not forget to mute when you leave…
