The correct answer is "C"
As with any employee, it is important not to jump to conclusions, but the situation still needs to be addressed and not ignored. Oftentimes company policy requires attention to such circumstances, however, disciplinary action is not always the answer. Every employee has a bad day at work, and this is no different. The same workplace practices you use in managing any co-worker can be applied. Highlighting a Veteran's experiences or the possibility of invisible injuries may be inaccurate, cause tension and/or be considered discrimination.
