When Alli, a University of California-Davis student who prefers to be known only by her first name, first got to school, she assumed she would eventually get a retail job like the one she had previously held at a Hollister. Instead, a fellow student alerted her to the existence of a delivery app called JoyRun through which she could earn money delivering food to other people on campus. To earn that money, she set her own schedule, working three or four hours a day, four or five days a week, without having to answer to a boss and often in the company of her boyfriend, who can accompany her on trips. And she’s thrilled. Her income goes towards immediate needs, such as textbooks, supplies and car insurance, as well as towards the future in the form of savings. She’s even able to pay down her student loans.
