Some back injuries can be covered by the Disability Discrimination Act.
The Act makes it against the law to discriminate against a person because of disability. There are some limited exceptions and exemptions.
Example: An employer dismissed an employee driver after he had a back operation. This could be disability discrimination.
It is not unlawful to discriminate against an employee on the basis of disabilities if the person cannot perform the inherent requirements of a job after reasonable adjustments have been made.
