I recently graduated from college. Because I couldn't find a paid position in my field (fashion design), I took an unpaid internship. I was promised plenty of hands-on experience and opportunities, but the only things I've had my hands on are the copy machine, my employer's dogs and kids, and groceries. I am doing almost nothing related to fashion, and instead am basically serving as a gofer and household help to a couple of the designers. Is this legal?
The answer is no. Calling a job an "internship" doesn't relieve an employer of the obligation to pay for your time. An employer that wants to pay less than the minimum wage (or nothing at all) to an intern must meet a strict six-part test, intended to ensure that the position really is a learning experience. If a job doesn't meet this test, the person holding it is entitled to be paid.
Unfortunately, you've run into an increasingly common problem these days, as the job market continues to sputter along and new college graduates can't find entry-level work in their fields. Some employers have decided to take advantage of the huge glut of potential employees by creating unpaid positions to get their work done free. Especially in fields that are competitive and glamorous (like yours), employers have been mostly getting away with this cheat.
But that doesn't make it legal. Interns are supposed to be temporary workers, typically students or people who are new to the field, who take a position to learn what a job is like and get some experience. If an employer doesn't pay an intern at least the minimum wage for each hour worked, the internship must meet a six-factor test created by the federal Department of Labor. The Department looks at the factors listed below to decide whether an internship is really a benefit to the intern or is actually benefiting the employer:
As you've probably noticed, your "internship" meets exactly none of the requirements on this list. You are receiving no training, supervision, or benefit from your work. Not only are you doing entry-level office work, but you are also being pushed into service as a baby-sitter, dog walker, and delivery person for your employers. If you were attending meetings with clients, going along on shopping excursions for fabric and materials, observing the design process, learning how to fit models, and otherwise learning your trade, your employer could ask you to fetch the occasional cup of coffee or copy marketing materials without jeopardizing your internship. However, your employer is providing no learning experiences, and instead is requiring you to do work it would otherwise have to pay for. This is illegal.
