In the article it mentions that this is a union of 70,000 independent contractors. I imagine that it would be very bad for Uber if they all decided not to drive simultaneously.
With collective organization, the union has a better chance to coordinate strikes and other collective action, as well as bargain for pay collectively rather than in a one to many relationship.
But anyway, even though Uber might lose some sales in the short term while they build up more drivers, if the union’s demands would make the rides barely profitable (or where Uber loses money) then that’s not really an actual loss.
Not to mention it’s the drivers who still pay depreciation and insurance cost of their cars whether or not they drive.
Similar to another commenter I don’t really care or have a dog in this race, I’m just commenting on the actors and what their relative advantages are.
I personally don't care about this as long as the costs aren't passed on to me.
So what? Uber operates all over the world, losing some revenue (maybe not even profit) in one region is a loss they can eat. A Taxi company couldn't eat this kind of loss and would be forced to negotiate. Uber though? They can tough it out if it's advantageous to them.
This is the inevitable result of replacing local taxi monopolies or cartels with a multinational "tech" duopoly.
