Illnesses can be covered by the definition of disability in the Disability Discrimination Act. Illnesses do not need to be permanent to be covered by the definition of disability.
The Act makes it against the law to discriminate against a person because of their disability. There are some limited exceptions and exemptions.
Example: A workplace gave its employees awards based on attendance, making an employee with a serious illness ineligible for the award. This could be disability discrimination.
It is not unlawful to take measures in relation to infectious diseases which are reasonably necessary to protect public health.
It is also not unlawful to discriminate against an employee on the basis of his or her disability if the person cannot perform the inherent requirements of a job after reasonable adjustments have been made.
