Earlier this week, several thousand workers who shuttle groceries on the app Instacart went on a 3-day national strike, demanding the app change it’s default tip from 5 to 10 percent. Yesterday afternoon, in what workers say is a rebuke to their organizing, Instacart declared that it will eliminate a $3 “quality” bonus given to shoppers who receive 5 star ratings from customers.

Instacart’s reason for cutting the bonus suggested workers weren’t performing highly enough to deserve it.
