This is a 20-page primer on gender fairness aimed at aiding Philippine-based business support organisations and the volunteer business advisors in addressing aspects of management and business operations that can be enhanced through gender-fair business practice. The primer provides specific strategies and resources for the actual practice of gender-fairness in business settings. It synthesises material on topics such as hiring, sexual harassment, leadership training, to advocate for gender fairness in the workplace. This primer was written as part of the Gender Fairness as Good Business project with PEARL2, which is funded by the Canadian International Development Agency's efforts to promote the growth of small and medium-scale enterprises in the Philippines.
