I think there is a dichotomy, but I don't think it's meaning vs happiness. Rather, it might be people who find meaning in what they do for a living, vs finding meaning in what they do outside of work. The key, I think, is identity; your answer to the question: "what are you?"

Happiness is a more complex question, I'd refer people to Maslow's hierarchy of needs. I'd add that happiness is usually fleeting, contentment and engagement with life is more achievable.
