If your wife does not have a written employment contract which has terms applying to this situation, she could be fired at any time, for any reason--including that the employer does not wish to let her work remotely. The employer is also allowed to change its mind about her job, her duties, her location, etc.--that is, having agreed initially to let her work remotely does not prevent them from saying "no" 5 days later. This is all part of being an "employee at will" (no written contract): it literally means whether, how, where, etc. she work is at the "will," or discretion of, the employer.It does appear that your state will let your wife be eligible for unemployment compensation if she loses her job due to your relocation, but you don't know for certain if you'll get it until you apply. I urge your wife to apply for unemployment if/when she loses her job.
