Some of these job sites use keywords to offer options to what you are intersted in. I get all kinds of oddball notices because one of the words was facility.
I work for my federal govt. Despite of all the BS I have to put up with, its a job and a full paycheck, every payday. If anyone out there is cosidering working for Uncle Sammy, I would glady answer any of your questions. Each agency works in their own weird way so I will try my best. The following link is off of fedjobs.gov, the offical website for federal jobs.
