Your coworker with the same title earns 56 percent more, and it is not talent, luck, or politics.
Data from close to a billion job postings shows exactly which four skills employers pay premiums for: AI fluency, complex problem-solving, communication, and leadership without authority. All learnable, and most people are deliberately building none of them.
This book turns the data into a 30-day system built inside your actual job: the fifteen-minute Leverage Audit that names the skill capping your pay, one skill built per week, and an Evidence Log that turns thirty days of work into the documented file most professionals never build in a decade. Every statistic is from a named, checkable source, and every premium is an honest market average, not a promise. Stop competing on effort in a market that pays for leverage.
