Why should he care about whether or not you are supporting a family? That is simply not his job, and that is not the mission of the company. You are paid an extremely handsome income and benefits, in exchange for your services. When those services are no longer needed, you should be dismissed. Think about it, when you need a plumber, he does the job, you pay him, then he is gone. You dont continually employ him so that he can take care of his family.
If you wallowed away in a blameless rep job for years, and did not dvelop your marketability, that is your fault. Does you wife work? If not, whose problem/fault is that? it is none of the companies business. AZ is in business to make money, and enhamce shareholder value, first and foremost. They are not here to provide jobs, or to ensure that you can support your family.
