The general rule is that employment in the state of North Carolina is "at will" absent an express agreement to the contrary. At will employment can be terminated for any reason not amounting to discrimination on the basis of a legally protected trait (race, religion, gender, etc.) or retaliation for engaging in certain forms of legally protected conduct (filing a wage claim, taking FMLA leave, etc.). It doesn't matter whether the basis for termination is fair, reasonable or even true.
So, there is nothing illegal about being targeted for termination based on financial trouble or for other unwarranted reasons. It is only illegal to be targeted because of a legally protected trait or activity, as defined above. This is why I am asking what makes you believe your husband is being targeted because of his age. If he is fired and he can prove that it would not have happened but for how old he is, that would be illegal. It's really the only basis for a potential legal claim based on what you have described.
So, your husband really needs to consider what evidence he has of an age bias. Are there derogatory comments being made about how old he is? Does the company tend to only hire younger employees? Are older employees being disproportionately targeted for termination and discipline? These are the kinds of things that need to be looked at and considered. But ultimately, an age discrimination claim comes down to one thing: can you husband convince a jury, based on all the relevant facts and circumstances, that he would not have been fired if he was younger? If the answer is "yes," then he has a potential claim. If the answer is no, then his termination would likely be permissible under the employment "at will" doctrine.
