Legal Question in Employment Law in Arizona

You might. Possible claims include breach of contract or promissory estoppel (an equitable claim that allows you to enforce a promise relied on). Maybe negligent hiring. The Arizona case on point (last time I looked) said, if the employee-to-be had actually moved, incurred the costs and life disruption, then he would have a claim. So, the legal issue is whether your reliance is sufficient. It is not a definite "No," which is good because ambiguity is leverage. But, what causes most of the cases to fail is that the injured party (you) does not have the money and/or desire to spend money on attorneys fees. It is almost certain that you would be out $10,000.00 or more before we could achieve a settlement. Cost to start would be much less, but it is the process that works and that can be expensive. In any case I am sorry to hear of your loss and good luck to you.
