A class-action lawsuit alleges that Mary-Kate and Ashley Olsen failed to pay about 40 past and present interns who have worked for them.

The lead plaintiff in the Manhattan Supreme Court case, Shahista Lalani, says she was treated poorly, performing menial tasks for free while working for the twins’ fashion empire, Dualstar Entertainment Group, in 2012.

Lalani says she worked 50-hour weeks and was hospitalized for dehydration as a result of the job.

The lawsuit says there are many other interns in Lalani’s position, and they should have been paid the minimum wage plus overtime because they were doing the same type of jobs as their paid colleagues without receiving academic or vocational credit.
