Are there any brands you'd refuse to work on? Even if it meant losing your job?
It's easy to say something like 'sure, I wouldn't work on cigarettes', but can you truly say that, hand on heart? If your agency was pitching for Marlboro, would you flatly refuse to get involved?
Where do you draw the line? It would be easy to say that advertising doesn't really make a difference anyway, but you don't believe that, otherwise you'd find a different industry to work in. Either that, or you've got a record breaking lack of motivation.
It's an interesting philosophical game to play. Which clients, if they dropped in your lap with job prospects attached, would you refuse?
