Modern workers are at the mercy of ratings
I get that its immeasurably frustrating for a person to be distilled into performance metrics, but how else can we measure one's impact? Using a trust based method where a supervisor leans on their personal biases to determine an employee's value is fraught with issues as well. A large enough corporation is a machine and we can't base decisions off of how we "feel" the machine's parts are working. Hard numbers will win over time.
