Workers' Compensation - Psychological Injuries
The following explanation on psychological injuries is from the WorkCover NSW Web site on Eligibility or and Lodging of a Workers Compensation Claim.
Psychological injuries are compensable if there is medical evidence that employment was a substantial contributing factor.
A claim for psychological injury can only be made if there is medical evidence to support that, as a result of your employment, you suffered from a psychological or psychiatric disorder.
No compensation is payable for a psychological injury if the injury was wholly or predominantly caused by reasonable action taken or proposed to be taken by or on behalf of the employer with respect to transfer, demotion, promotion, performance appraisal, discipline, retrenchment or dismissal of workers or provision of employment benefits to workers.
You can lodge a claim with your employer's insurer, but you will require a medical certificate stating a diagnosis of your condition (ie. specific symptoms) described in suitable medical terms and the doctor's opinion as to wether your work was a substantial contributing factor to the onset of this condition.
Note: The word "stress" is an insufficient diagnosis of your condition for the purposes of making a claim for workers compensation.
