I'm pretty much responsible for myself but I shouldn't goof off as much as I do (i.e., post here!).

About the guy who got fired--I would have started doing something, anything, just so I'd have something to say if I ever got caught. "Oh, yeah, this is what I was told to do. I inventory the shelves, restock them, and stay in touch with repair services..." Or whatever shit seemed appropriate. "I didn't get any further instructions, so I just thought I was supposed to pick it up on my own." In other words, make it look like you DID use some initiative but apparently didn't get it right because management failed to follow up with you.

Or go and look at what the job description said, at least, and know enough to say that's what you'd been doing, even if you weren't.
