This document discusses various biographical characteristics that can be identified in the workplace, including age, gender, race, tenure, religion, sexual orientation, and gender identity. It notes that older workers bring experience but productivity may decline with age. While few gender differences impact job performance, women prefer flexible schedules, especially those with young children. Race can impact opportunities if people identify more with others like themselves. Tenure is often seen positively as a sign of job satisfaction. Religion may impact dress and grooming standards. Sexual orientation and gender identity lack federal protections and are handled differently by employers.
