Doesn't annual hours worked suffer from "measure as a target" issue among other things? There frequently are incentives to misreport it based on company culture or perception among coworkers. Nor does it actually correspond to 'productive' hours. I can tell you for a fact that while my coworker is physically present for about 40 hours a week, they realistically perform job duties for maybe about 15-20 hours out of that, and that's being generous.
