Discrimination and harassment violate professional standards and human rights laws. Discrimination involves unfairly treating someone worse due to characteristics like age, gender, or disability. Harassment involves offensive behavior or comments. If witnessing harassment, one should stop it if possible or report it, carefully documenting details. Stereotypes can lead to discrimination if not checked. Organizations should establish clear anti-harassment policies and procedures to address complaints in a confidential and impartial manner. All should aim to treat others respectfully regardless of personal attributes.
