All good suggestions, but heavily focused on non-collaborative solutions. For example a paper calendar is no good if you regularly use your colleagues calendars to schedule events and know what is going on.
It's a weird combination of laziness and an unwillingness to use other tools (email, issue tracking, typing). If they just typed up an agenda (heck, Confluence has a template ready) we could probably wrap up the whole thing while I'm goofing around on HN.
Having to go through an EA/PA to schedule meetings is one of the best ways of exchanging money for time, plus you end up having one person who never makes you cringe, unless you start worrying that they're giving notice because they're starting their own company or moving across the country.
