Alvarado likes to start her shift in the parking lot of the massive Whole Foods Market on Chicago’s Near North Side, where Instacart orders are plentiful, watching her app as she sits in her Kia Sorrento. The job is ideal for her, she said, as she likes to shop — driving for a ride-share platform like Uber would make her too anxious — and it can hold her over while she waits for her GED program to start in January. She hopes to study criminal justice and become a youth parole officer.
