That's you. But for many people, that style of interaction just doesn't mesh with their personality. Some people are more meek, and won't tell you about an issue until you ask them straight out "what's up?" in a setting where they know that's their time to speak up. If you don't have a scheduled recurring 1:1 with those people, they won't schedule a time to meet with you. Until they schedule a "here's my 2 weeks notice" meeting with you.
