Change provisions relating to veterans preferences for employment

This bill updates Nebraska's veterans' employment preference rules. It clarifies definitions for "veteran" (including spouses of disabled or deceased service members) and requires state employers to give preference to eligible veterans in hiring, reassignment, and promotions. For private employers, it allows voluntary written policies to prefer veterans, while specifying that applicants must provide documentation like a DD Form 214 or VA disability verification. The changes apply to all state government jobs and private employers who adopt the policy, directly affecting veterans and qualifying spouses seeking employment.
