I definately run a business. Absolutely, if I didn't cover all the bases then my business would cease to exist. Theres more to running a business than turning up and cleaning glass; when you do that you're running a business.
Brickies are self-employed, they turn up, lay bricks, go home. I employ someone, he's self-employed or on the cards, it's irrelevant. He comes to work, cleans glass, goes home.
