In this Manager Lab episode we unpack a new HBR study that shows foundational or "soft" skills—like communication, adaptability, critical thinking and basic numeracy—are more important than ever as AI reshapes work.

The research analyzed nearly 1,000 occupations and 70 million job transitions to reveal a nested skills structure: general foundational skills support intermediate and specialized skills, and roughly 80% of the wage premium from advanced skills comes from those foundational abilities. The episode also highlights "skill entrapment" and equity gaps that limit access to higher-paying pathways.

Practical takeaways include auditing your core skills, practicing nested learning (build the base before specializing), integrating soft-skill practice into daily routines, mentoring early-career talent, and advocating for training that prioritizes fundamentals.

The bottom line: strengthen the trunk of your skill tree to future-proof careers and create more equitable opportunities across organizations.
