It's USAJobs.com that you want to take a look at.
If, as a civilian employee, you have paper orders changing your location, and they state that you have a relocation allowance (usual), you would contact your closest Personal Property Shipping Office and they will arrange to have commercial movers pack, pick up, move, deliver, and unpack your stuff. ALL of it. At Government expense.
PM me if you should need info on your closest installation PPSO.
Bennies for civilian employees are great. You have to go to a lot of meetings, of course, but the retirement is good, you get to use the BX/PX and commissary (CHEAPER THAN KROGER LEMME TELL YA), lots of vacation and sick leave. And the more years you are on the job, the better of course. It doesn't top out the way normal jobs do.
Some things to keep in mind: Background check for clearance. There are several levels of clearance, from Network Access Clearance to TOP SECRET. They will ask a LOT of questions. When I got my first clearance I had to find out where my ex husband lived. THAT was interesting. Financial problems do not necessarily result in denial of clearance, depending on what you're doing. I had a bankruptcy on mine. But I don't work with money.
Expect federal agents to ask your friends and family questions about you! That was fun, letting my friends know that "MIB" would be calling. Still wonder what exactly they were asked.
Does this help any? Oh, I'm only a CONTRACTOR, not a civilian...
