Despite the importance of Labour Market Information (LMI) to career practice, there is a surprising lack of theory that focuses on LMI and how it supports career guidance. Building on previous work, especially by Staunton and Rogosic (2021), this paper will argue for a move toward a critical realist account of LMI that sees it as historically and politically positioned, rather than objectively verifiable on its own terms. This opens up new possibilities for how career practitioners can make use of LMI and fresh avenues for theory and research.
