Uber works differently. The driver chooses when and how many hours he wants to work and when to pick a ride. If what was decided above applies for every uber employee its not gonna go down pretty well cause :
Uber is going to become one more minicab agency, where it employees people with a schedule and its price is going to go up by a lot.
Customers won't benefit and drivers won't either.
Most of the drivers I've spoken to and I use Uber a lot have told me that the job is not as great or the pay depending on the amount of time they work and if they are actually renting a car or having a car on lease or own it, the thing that everyone told me is that they get to work whenever they want and thats awesome about it.
Apply rules to the Uber is gonna force rules to be applied to drivers as well and thats not gonna go well.
