I have a degree in journalism and I'm working in the medical field. However, my department is "marketing" but it also includes advertising. Too bad I opted not to take the advertising classes offered. I could use them now.
I do agree with Soror AKA2D that internships and work experience are very helpful. Although I did not work during the school year, I did have summer jobs. My campus had a career center that listed available internships and employment for students. I would encourage you to use whatever resources your campus may have.
However, think carefully before taking a teaching position just to have a job. I think it is great to take education courses, but please don't do it just to have something to "fall back on". I know a few people who took on education as a second major or as a minor "just in case", but were not really interested in the profession.
Our children are being short-changed in some instances. We don't need more teachers who are more concerned about a paycheck than the minds they are helping to nuture. However, if you find that teaching is your true calling then I encourage you to follow your heart.
