Hire a crowd worker (upwork worker, uber/lyft driver, Mechanical Turk worker, TaskRabbit worker, etc.). Ask them about why they work through that crowd platform and what kind of work they do. Ask them about how they have been treated. Ask them whether they believe the crowd platform they are working for is better or worse than other jobs they have held. Ask them how the crowd work platform could be improved.
