That's quite a myopic view of things. Going above and beyond may not offer an immediate pay increase, promotion or more break time, but it will afford him an opportunity to learn new things, show that he is fit for more responsibility, and in the process he'll stand out to all those working around him. All this will increase his chances later down the road of getting where he wants to be. Most importantly, it will address his immediate problem of boredom!

His alternative: Do what his job description says, surf the internet, watch the paint dry... sounds like a real recipe for motivation, excitement, and success.
