Knowing why the limit exists tells you exactly how much trust a long-range forecast deserves.

Behind every promotion and every quiet exit is a system, and companies run very different ones. The approaches here range from continuous strengths-based feedback to Netflix's blunt keep-or-cut test, with sharp critiques of forced rankings, annual reviews, and using OKRs to judge individuals.

Where you land shapes which relationship advice you take seriously.
