As a normal worker this subject is highly important to me, but I think the writer misses the differentiation between a job and an occupation. The latter is not just 'work' but forms an extremely important part of one's life - it even defines one's life. So if your work is effectively a large part of your life, how can you talk in a normal way of work/life balance???
