Do you mean "Should a driver still have a vote/share in the co-op if they quit driving for 6 months?" If so, then there are various ways to handle it. I'm not an expert but in agricultural co-ops like Oceanspray, the problem simply doesn't arise: there's no scenario where it is in the farmer's best interest not to harvest his cranberries at all, and they contract for delivery before the harvest season (they can go it on their own or sell to a different processor next harvest if they want, in which case they leave the co-op). For worker co-ops like grocery stores, there are various solutions: some give credit (including voting power and dividend) per hour worked, others just pay regular wages but have tiers of ownership that you move up with tenure. There are infinite possible models. For Uber specifically, I can see miles=votes for each election period. IOW, if you've driven 10,000 miles since the last election, then you get to cast 10,000 votes. The fact that all the work is tracked mechanically makes it easier in Uber's case than in others.
