"Instacart Workers Are Striking Because of the App’s User Interface", 5 November 2019

Several thousand workers who ferry groceries for Instacart are on...a 72-hour strike over how the on-demand delivery app pays them. Instacart’s “shoppers” ...have a problem with how the platform manages tipping:

The default in the app is for users to leave either a $2 or a 5 percent tip for the shopper on top of the 5 percent service fee that Instacart charges every order. The workers allege that this service fee is misleading and that the 5 percent default tip option has cut into their take-home wages—which they say have shrunk because the app previously suggested a tip of 10 percent, and the company didn’t charge a service fee...

...another crucial design choice might be that the app doesn’t indicate that the tip it suggests is only 5 percent; while users have the option to manually enter a higher tip, they may not realize that, by percentage, the default is paltry...
