Employment in a dream may mean that someone has accepted who they really are and what they are meant to do with their life and have given up on making unrealistic goals.
In most dreams involving work, work itself is the major player in the story and what dictates what happens next. This may be related to your own life or personal history where you might have been struggling with finding work because there was not an adequate supply of jobs available at your age or experience level.
Employment can also be a reflection of your own hopes, fears, or ambitions.
