I'm at work. Or: I'm at the BBC right now. 'On' is used in relation to a surface. I'm sitting on a chair. And 'in' is used to talk about a three-dimensional space, usually with four walls. It's similar to 'inside'. I'm in a room. So to help you remember these rules, try to think of a concert: I'm at the front. The band is on the stage. And my friends are in the crowd. And where are you right now?
