There's a growing push for a future relationship between Uber and the unions, including collective bargaining. 

Four drivers have officially won their battle to be recognised as employees in a Supreme Court ruling announced today. 

Uber argued they were contractors. 

Workers First Union deputy secretary, Anita Rosentreter, says the Employment Relations Authority can now calculate how much Uber owes other members. 

"But what about the system going forwards? Clearly, it's not been working for people through the collective bargaining process, we really want to improve the Uber system for all drivers."
