Discrimination law applies to all workers, whether you are getting paid or not.
When you go on a work experience placement, you are entitled to the same protection against discrimination, sexual harassment and bullying as the paid staff. The same is true if you do volunteer work.
If you are discriminated against, bullied or harassed on a placement arranged by your school, let the school know straight away. They should take it up with the employer. If necessary for your safety, they should end the placement. The school should not send any other students there until they are sure the problem is fixed.
If you are discriminated against or sexually harassed, you can also lodge a complaint with the Equal Opportunity Commission.
An employer doesn’t need to pay you when you are doing work experience through your school but if an employer engages you directly to do a trial shift, they do have to pay you.
