The HR partner needs an explanation for a mismatch between active-worker and filled-position counts. Preserve both registers, summarize assignments, quantify distinct position conflicts and nonroot manager exceptions, then choose the conclusion supported by that evidence.
The HR partner's active-worker count doesn't match the filled-position register. The worker data includes a missing manager and one position assigned to more than one active person. Those are separate exceptions. Fixing the manager label would not reconcile the position grain, and counting position titles would not identify the assignment conflict.
Build both sides of the evidence. Keep active worker IDs with their position IDs, then inspect the position register and summarize active assignments. Count the distinct conflicted position IDs and the nonroot manager exceptions separately. Your final conclusion must explain why worker and position totals can't be substituted for one another. The case preserves the reports and checked counts so the recommendation has visible support. No source record is changed in this investigation.
