A University of California, Berkeley labor center study found that when full time spent working (including wait time) was counted, the guarantee amounts to $5.64 an hour, less than half the state minimum wage.

The UC Berkeley Labor Center also estimates that after factoring in waiting time, expenses, and taxes, this wage floor established by Proposition 22 would, in fact, come out to $5.64 an hour, far less than the current state minimum wage of $12 an hour ($13 an hour at larger firms like Uber and Lyft).
