Injuries can be covered by the definition of disability in the Disability Discrimination Act. Injuries do not need to be permanent to be covered by the definition of disability.
It is against the law to discriminate against a person because of his or her disability. There are some limited exceptions and exemptions.
Example: A warehouse supervisor, whose job mostly involved sitting down, had an injury which resulted in restricted use of his leg and spine. His employer dismissed him because of his injury without making adjustments to assist him to do his job. This could be disability discrimination.
It is not unlawful to discriminate against an employee on the basis of their disability if the person cannot perform the inherent requirements of a job after reasonable adjustments have been made.
