Most drivers that I have spoken to during my hire, say they are not paid a fixed monthly salary, rather they have to deposit a certain amount with Karwa at the end of the day. Anything made over that amount is what they earn for the day.
If I remember it right, that amount was QR 260 before the fare hike. I guess this amount will go up as well, in which case the poor cab drivers will continue to struggle for a worthwhile earning.
