In papers filed in Manhattan Supreme Court, Lucy Bickerton says that she worked 25 hours a week as an unpaid intern for the “Charlie Rose” show over three months in 2007 and that she should be paid.

“Unpaid interns are a crucial labor force on the ‘Charlie Rose’ show, where up to 10 interns are employed at any given time” and “perform background research. . . escort guests through the studio, break down the set,” and clean up the area where guests await their interviews after each taping, the suit says.

It contends that “the practice of classifying employees as ‘interns’ to avoid paying wages runs afoul of state wage and hours laws.”

It seeks class-action status on behalf of all of the TV talker’s unpaid interns since 2006.
