Employers can discriminate against employees, or prospective candidates on the basis of superficial attributes such as hair colour, make-up, piercings and tattoos. It is unfair to subject innocent, hard-working citizens to this prejudice and unjust treatment in the workplace on appearance-based grounds, especially without any legal means to challenge such discrimination. Nobody should be made to feel inferior or disadvantaged due to harmless self-expression. Appearance doesn't define ability.
