Dave,

I believe Check6 is correct in that the first year is usually a probationary year, one in which the company can fire a person for virtually anything. Usually the union would have gotten involved prior to a termination procedure, but a new hire is an employee at will, and as such, is not provided for (except in pay scale) under the "contract." There are no dues required or expected during the first year. Being a 24 year Air Force pilot, I'm sure you're not 100% excited about working in a union environment, but hopefully you'll see the need and realize the benefits you gain from working in a union shop.
