How much will dropping out of a Master's program hurt job prospects? I am extremely dissatisfied with the Master's program I just began and plan on dropping out ASAP. I currently have no interest in finding another graduate program and instead wish to pursue a job outside of academia. As I see it my two choices are to either stick it out for the rest of the semester and just try to maintain C's, or to simply walk away from it and accept the F's because the drop deadline has passed. 

The main question I have is how much more damaging is the option of just walking away mid-semester? 

I realize that certain employers will view the situation differently, but I am just seeking opinions here. I have no idea of what industry I would want to work in or how that might affect your answers. Or if anyone has advised students in similar situations, I would greatly appreciate similar advice. 

As for my records before this program, I got my BS in applied math and graduated with honors. I am hoping that I can bank on this earlier performance and explain the reasoning behind dropping out to potential employers.
I would stick it out and get the best grades I can.  I would try to monitor my stress level and do things I enjoy as well.  The important thing is to finish things in a clean way and not let yourself get to the point where you drop everything and leave.

The job market is extremely competitive these days.  A master's degree can have a big effect on what pay you receive and how far you can go in certain industries.  You might not feel like a master's degree is worth it now, but you might want to go back to school for a different degree or even to complete the same degree.  It's hard to predict what the situation will be for you in 5 years or 10 years.  Bad grades now can restrict your possibilities for years to come.  Who knows? You might be thinking about getting an MBA in a prestigious program in 10 years and find yourself stuck having to explain some bad grades from years before.

Your first one or two years of work, people might ask about your GPA as well, and leaving the graduate school off might be tricky as it might leave gaps in your employment.  Although, I have seen it work to just not put what year you got your undergraduate degree.
