I'm a veteran who was put out of my work building without just cause. Now my company is keeping me out how do I proceed

There is not enough information here to give you any meaningful guidancce.  However, with more information, we would only be able to give you general guidance.  You would likely still need to consult directly with an experienced employment attorney. Even so, in broad terms, if you work for a private employer in North Carolina, there is no requirement that the employer keep you employed as all employment is at-will. That means you can be fired at any time for any reason.  The same applies with a return to work.  There is no legal claim unless you can show the failure or refusal to return you to work is based on an unlawful motive.  I do not see evidence of an unlawful motive here although things such as FMLA retaliation or an ADA violation could be possible if your situation is covered by either law. I mentioned specifically a "private employer" which means a non-governmental employer.  Some diference rules can apply to some governmental employers such as the State of North Carolina.
