Yes ... there's plenty of places you can get a job without a GED. Of course, most of them are minimum wage jobs. Unfortunately, most trade jobs today (mechanic, electrician, etc) even require education beyond high school.
Yes, its possible. However, the job market is a competitive place. Without a diploma or at least a GED a lot of doors will be closed and you will make a lot less money in the long run. Get your diploma or GED if this is at all possible.
