The Fair Work Act 2009 is the most important act with respect to employment relations and the Human Resources topic. It determines terms and conditions of employment and sets out the rights and responsibilities of employees, employers and employee organisations in relation to that employment. You should definitely ensure you have a good understanding of what the FWA covers and to whom it applies.
The NSW Work Health and Safety Act 2011 is also an important act to remember because it provides a framework to protect the health, safety and welfare of all workers at work. It also protects the health and safety of all other people who might be affected by the work, making it an important element of the Human Resources topic, because safe working conditions are a crucial component of employment for a business and its employees.
With respect to anti-discrimination and equal employment opportunity, it wouldn't be a bad idea to familiarise yourself with one, a combination of, or all of the following laws:
Affirmative Action (Equal Employment Opportunity for Women) Act 1986: as suggested by its name, this act aims to promote equal opportunity for women in employment.
Sex Discrimination Act 1984: This act promotes gender equality in Australia by prohibiting unlawful or unfavourable treatment of a person on the grounds of gender, marital status, sexuality and pregnancy. It also makes sexual harassment against the law and protects employees from being dismissed because of family responsibilities.
Anti-Discrimination Act 1977 (NSW): this act shares some similarities with the Sex Discrimination Act 1984 and also covers discrimination based on age, race and disability. The main difference is that this act is effective within NSW.
