Well depends on what job I guess, but I think in this time and age it is pretty important. The Air Force wouldn't allow you in without one. I know a lot of jobs feel the same way about having at least a GED. If you don't have one there are adult schools for people to get their diploma at, should have one some where near you, if you live in a decent sized town or city. If not they have online classes too I believe, it is pretty fast and easy.
