It would be better if, instead of using a distilled and ambiguous code word like "passion" (that several people on this thread are expending valiant effort to explain/define) employers just came out and said what they mean/want. "We're looking for people who do their work with care and attention," or the like. Passion is a whole can of worms. Passion can be sex, rage, irrational attachments to things you're "passionate" about, or boundless totally disruptive joy. Is that what they want in the office? I doubt it.
