A Sydney delivery rider has gone to the Fair Work Commission to sue delivery giant, Deliveroo, on the grounds of unfair dismissal.

Deliveroo stated Diego Franco frequently took significantly longer to complete a high number of deliveries, and issued him with a dismissal on 23 April.

Diego Franco, who moved to Sydney from Brazil three years ago, contends that his deliveries were slow and that he did not receive any notification before his contract was terminated.

He claimed that the company has unfair policies towards its workers, and the claims in which he has been dismissed for are contestable.

The legal action he has begun is likely to put other food delivery companies under scrutiny for their company policies.
