SAN FRANCISCO — Sprig Inc. is the latest on-demand company to face litigation over its practice of labeling its workers as independent contractors.

The San Francisco company, which boasts “healthy, organic meals delivered in 15 minutes,” uses an app to dispatch “servers” who deliver customer orders. The servers should be classified as employees, according to the complaint filed Friday in San Francisco Superior Court, because the company exercises significant control over their work. Instead, by misclassifying its workers, the plaintiffs claim Sprig denied them benefits including minimum wage, off-duty meal periods and reimbursement for work expenses.

“Despite Sprig's extensive right to control,” the lawyers wrote, “Sprig willfully and intentionally misclassified its servers as independent contractors.”
