Couldn't have said it better Robert-C7!

Larryritchie, the lesson specifies you'd be addressing a co-worker, so most likely there is a formal environment. However, it all depends on the closeness you have towards the person you're talking to. If the person is a co-worker and also your friend, you can translate it as "tú".
