My niece is commuting to London from Sussex every day for her internship working for the fasion industry.
They have made it clear she is not part of their team - they ignore her apart from telling her what to do - and have her running about all over London returning items, etc.
She gets nothing and saves them hours of work, I know internships are ways of getting into some industries such as publishing, journalism, etc, but they should at least refund her travelling expenses
