There's hopes a ruling against Uber could help empower other contractors.

The Court of Appeal has ruled four Uber drivers are employees, not contractors.

Uber says it will appeal and claims the move will increase uncertainty for workers who enjoy the flexibility of contract work.

First Union General Secretary Dennis Maga says it could have wider implications.

He says while likely limited to other Uber drivers at the moment, the ruling could help other contractors make their case.
