Sociology assignments

I have a question based on one of my Sociology assignments. I am confused as to how to answer this question becuase it seems vague to me. Can someone please clarify what the question is asking and what would be the best way to answer this question accordingly? The question is:

Many commentators argue that job selection and working conditions are matters of individual choice and free markets. Using your own experience or empirical evidence, indicate whether or not this is a valid argument.
