Micromanagement isn't about frequency of contact so much as the amount of control the worker has over their work. The biggest micromanager I ever worked for would forget I existed for days or a week at a time, only to come in tell me to throw out hours of work and do very specific, arbitrary things instead because he just liked it better a different way. The most hands-off boss I've ever had would drop by for a chat almost every day, but mostly just to get thoughts on overall direction and discuss ideas he was mulling.
