I find that difficult to comprehend. I really do. I mean, even a low-end job would be unpleasant to work in if I were drunk- say, doing CAD or running a machine- but doing something high pressure like designing chips? Doing that while *drunk*?!? GAH!

Even more difficult to comprehend is that the company would let him get away with it. If nothing else from a morale viewpoint that would be dreadful... not to mention the liability!
