When you are in the job hunt you want to "beat the bushes" for potential openings. Ideally you don't want to be looking on Monster.com or in the newspapers. Besides the other job sites, one that exists for government workers is Governing.com/jobs
I expect the majority of positions there will relate to non-emergency management openings, but then you never know! Also, if you are a manager who will be hiring, this is another place to list your vacant position and go beyond the local neighborhood to find quality candidates.
