My answer comes from my experience as a paralegal in Texas. You should really do your own regional research. Every state varies greatly on how they regard paralegals. You should also try to narrow your search to the area of law you are interested in. We all do different tasks and no two paralegals are alike.
With that said, I love my job, but I also work in a state that values their paralegals and treats them as professionals, not glorified secretaries. I personally do not know where Ohio falls in the spectrum and that is research you will have to do on your own. I suggest contacting a local paralegal association. The pros are working around intelligent people that are motivated and career minded, good benefits, always something different, no two cases are ever the same, and it is a challenge. There are always opportunities to become more than "just" a paralegal by joining the various national paralegal organizations or your local and state bar paralegal divisions. We do volunteer work, socials, continuing legal education and do whatever it takes to keep the career feeling fresh and not just a job. When you surround yourself with positive paralegals, the day goes faster and learn so much on a daily basis.
The cons? I'd be the wrong person to ask. I love my job. But with that said, many people find the education aspect a "con". There are no educational requirements for paralegals in the sense that some of us were hired with nothing but a high school diploma and some of us have bachelor's degrees. California is currently the only state that requires education. If you are misinformed that this is a job you can just start putting resumes for without some kind of education, you are wrong. More and more firms are realizing that paralegals need to have at least an associates degree. If you don't have one, it doesn't mean you won't get hired. Your chances will be much slimmer. You should attended an ABA approved program if you expect to get hired within a reasonable amount of time. Paralegal "certificates" are worthless unless you already possess a higher education to go in conjunction with the certificate.
I think the con I run into the most, and you will most likely experience it from other answers such as Mailaccount's, that there are a lot of people that love misery and want company. They beat down the paralegal profession because of their bad choices. They may have worked for a bad attorney that put them in very bad positions, but instead of finding another place to work, they stayed there 18 years and blame the profession. I hope you are intelligent enough to decipher the motivations of people. You can't blame the paralegal field for personal bad choices. You get people like Mailaccount that for whatever reason hate life and hate the legal field and will run and find every piece of propaganda to support their claims, to steer people clear of the legal field. All I have to say is I hope you don't base your knowledge on someone's negative opinion.
I love being a paralegal. I get to do quite a bit of legal work without the responsibility of signing my name on it. I am treated with respect. I chose a law firm that gives me great benefits. We are like a small family. I attend continuing legal education. I am a member of three paralegal associations and am working toward my bachelor's, my Texas Board of Legal Specialization in Civil Trial law and my Certified Paralegal designation. I am very driven, very motivated and I enjoy the daily challenges. If this doesn't sound like your personality, you may not like being a paralegal. Only you can gauge whether this profession will match your personality. Each area of law is different, so contact a local paralegals in the area of law you are interested in and ask! Maybe Ohio does not require you to have so many titles behind your name, but it is common here in Texas to go above and beyond. Good luck!
