Job prospect for civil

I am an undergrad in civil. I've heard the current job prospect for civil engineering isn't looking very good, especially in the structural side. So I am tempting to switch out. I am equally interested in mechanical and civil, however, my gpa wasn't good enough to get into mechanical. So instead I am considering transfer into General Engineering with a secondary field in Automotive Engineering or Robotics. Which one has better job prospect (civil or general engineering)?

General Engineering curriculum in my university consist of the following subfields:
* Automotive Engineering
* Bioengineering
* Business Systems Integration & Consulting
* Civil Engineering Structures
* Communications and Computer Systems
* Computer-Aided Design and Manufacturing
* Computer Science
* Construction
* Control Systems
* Engineering Administration
* Engineering Marketing
* Environmental Quality
* Manufacturing Engineering
* Nondestructive Testing & Evaluation
* Operations Research
* Quality Control
* Rehabilitation Engineering
* Robotics
* Theoretical & Applied Mechanics

Like I said, I am equally interested in both of these engineering disciplines, I am looking to compare which one has better job prospect.

Is here another field of engineering that is similar to MechE, that I can look into?

Another question: If I choose to stay in civil, which primary field has better job prospect (structural, geotech, environmental, construction management..etc) ?

By the way, I attend the University of Illinois.
