If this is really the case, you need to get documentation of this to Apple; it should simply not be possible.
Can you take the tech guy out for a beer or three, and ask him what he did?
And ooh, I know what you can do: Create a second account and copy all your data to that account. But don't delete the first account; keep the G4 user, and leave the existing data in the G4 user's home directory. Then set the user G4 to log in automatically.
Let your boss accidentally overhear that you've given up on keeping others out of your computer, and just went back to auto-login.
Then whenever your boss wants to get into your computer, he'll boot it up, get right into G4's account, and think he's messing with your stuff. Periodically, copy some of your newer stuff over into the other user's account, so that to your boss it continues to appear to be real stuff.
To keep the apps safe, install the apps separately into G4's Apps folder, and into your own. Then your boss can mess with "his" apps all day long, and not be messing with yours, even though he thinks he is.
And turn off fast user switching, of course. With any luck, your boss'll never realize that there's another user on there, and would have no reason to go poking around.
The downside would be, every morning after booting up, you'd have to log out of the G4 user account and log back in as your real user.
But seriously -- yeah, call Apple Tech Support. If this "one user/two passwords" situation is real, it's a serious security issue that Apple needs to know about.
