Most have been driving for Uber for a few months or a year. No more than that but it's a relatively new service so that makes sense. Most also say they love doing it. None have said they don't like it though there are some things they will sometimes say they don't care for. Some like shorter rides and they don't like when they take a long one, for example. But overall they love it. Are they fibbing? Who can say. But that's what they tell me.
It’s possible drivers are reluctant to tell passengers the truth. Although I’m sure some drivers actually like the work. But since driver and passenger review each other, as a driver I’d be reluctant to tell someone I hated my job! I certainly never told the truth when I worked in retail at the same time my husband was driving for Uber. Of course, there were aspects of my job that I really enjoyed...
