I had two past co-workers who were almost certainly having someone else do their work, I think (especially) at non-software companies folks just don't get caught. Frankly, the work environment was slow-paced and generally non-confrontational so both co-workers I suspect of this behavior just managed to tread water. When I joined the group there was a very tight-knit group of 3-4 developers who were very protective of each other. There was always a handy reason why some schedule was slipping and the other fact is that in hindsight, there just weren't very high expectations for them to accomplish anything.
