In 2017 DoorDash Inc. began including tips in drivers’ base pay. This means that drivers did not receive tips given through the app on top of their wages, but that the company was using tips to pay employees their base wage. Customer complaints and news coverage have led Doordash to reverse this policy, with more details soon to come regarding a new compensation plan. Amazon uses a similar wage model, which has led consumers to distrust web-based firms to tip employees honestly. In order to ensure workers are receiving their tips, costumers can choose to tip with cash.
