Phone sex might be expensive and short-lived for consumers, but it doesn’t pay much for the workers on the other line.

That’s according to a class action filed on Tuesday alleging a California-based phone sex operator misclassifies its “phone actors” as independent contractors, depriving them of overtime pay and “off the clock” work. As a result, the sex talk workers, most of whom are women, are paid below the federal minimum wage of $7.25 per hour in violation of the U.S. Fair Labor Standards Act, according to the suit, which was filed in federal court in Los Angeles.
