I'm with Marina on this one. Why can't tarot answer yes or no? It may come about through a descriptive answer, but the story told by a spread should make the yes or no evident.
If someone asks if they'll get a raise, maybe a three-card draw shows:
7 of Pentacles - Judgment - 10 of Pentacles
That seems like a yes to my way of thinking. The seeker's hard work will be noticed and rewarded.
If I am going to get the job - well, now I needn't bother going to the interview, right ??? See what I mean ?
I must disagree with your statement. Few people are going to NOT interview for a job because they were told they'll get the job. If they do, they have bigger issues than how tarot talks to them.
I think your example has more to do with general views of prediction and free will, rather than whether tarot can answer yes or no questions.
Want to empower someone with a yes or no reading? Take my example above and turn the cards into advice: yes, you are likely to get the raise, provided you continue to work hard and nurture your particular projects. Remember to trumpet yourself appropriately, and make clear what you are doing to be worth that raise. It will pay off in the end.
I think the original question about tarot should always have a follow-up: if tarot doesn't answer yes-or-no questions, what divination method does?
Horary astrology, for example, was and is used to answer these kinds of questions long before the paper to make cards ever existed. It answers them with aplomb -- in skilled hands, of course -- and gives a very straightforward story as to why the yes or no is likely. It was used in the past in all walks of life, and by many intelligent people whose well-being, if not lives, depended on answers and advice from the astrology. I doubt anybody ever said, "Sorry, astrology doesn't DO yes or no questions, so I can't tell you if that horse is a good purchase or who stole your family crest. I can tell you why you drew these things to you, though."
Many people are treating horary astrology as a serious and spiritual pursuit yet today. You can search the web and see this. Even in AT's astrology subforum. Why is tarot different?
Tarot doesn't have the same rules in place but does that mean it can't help the reader to intuit answers? Doesn't a story from a spread tell the outcome, provided the reader is willing to look at the outcome?
Visiting the Lenormand section of this forum will show many predictive readings and nobody asks whether yes-or-no is feasible. People don't have any qualms about using the Lenormand that way. Why is tarot treated so differently? Both are merely tools for accessing intuition and insight. They are pieces of stiff paper with symbols, which have conventional meanings. These meanings are grouped together in a reading to produce an answer. What is the difference in the medium itself?
Explaining the tarot doesn't do yes/no and I can instead give them the situations surrounding what will happen if the event will happen and the events if not with suggestions on how to make it happen.
As with any other kind of divination, it's not 100% guaranteed; we humans aren't omniscient. But your approach seems fine to me.
