I'm a student but I run a small business on the side with my friend, we own two vans which we converted to sell fast food (e.g burgers, hot dogs or fish and chips), these we(well I) use to market our goods at events (paying the organizers commission), usually we will run one, we split the profit however we recently purchased another and we have a Romanian immigrant working for us in the other van, he gets paid below the 'living wage' (though he only works a few hours on sat or sun, he has a job Mon-Friday).
Would you object to this and what/why specifically please. Perhaps you can convince me to change my operations.
