If you leave a New Hampshire state job to go on active duty, your position is held in inactive status and the state must rehire you into the same or a similar position within 90 days of your discharge.
Tell your agency's human resources office before you leave and give them your orders. Contact them again with your discharge paperwork as soon as your service ends, so the 90 day window is not missed.
Your military orders, and your discharge paperwork showing a discharge other than dishonorable when you return.
