What does the alternative look like? A contract for 10 rides? A contract for one week at a time? What if the driver wants to serve one ride, and then never again: what contract models allow that single ride to fulfill a "contract"?
The alternative is traditionally called a retainer. You hire the contractor for “various tasks over a set period of time up to N tasks and at least M tasks”
This is the indie version of being salaried. Very common among software engineers, for example.
First, Uber doesn’t have separate contracts for every ride.
If a contractor had a contract to accept or decline every jira ticket (although I don’t see anyone ever forming that contract), if they declines too many tickets they would no longer have the option to pick.
Could this be simply solved by having their star rating influenced by % ride drops? Uber can provide its price estimate as just that - a kelly blue book value so that riders can compare and contrast?
Most customers will search for a range of rating + price - so the market can regulate itself. I mean we accept amazon displaying user ratings - so I don't know why this won't work.
