How did you get into the field? I rarely see job postings for HR positions so I figure they're mostly internal hires.
I graduated college with a Bachelor's Degree in Business Administration. I was a management major with a minor in Human Resources (at my college that called them "certificates", but it was basically like a minor). I started out as an Office Manager who assisted the HR Dept. at my first job after college. Soon after, I moved up in their HR department. Now I work for my father's company, handling their HR work... but I worked for about 2 years at another company doing HR.
I can't speak for all states or all companies, but in my experience, I have seen quite a few HR postings out there. Some may be hidden under a heading of "administrative work" or something to the like. Also, SHRM (the Society for Human Resource Management) has postings in HR arranged by state and level of experience from entry level to upper management.
Did you have specialized education? ie MBA/HRM? Is it worth it to get specialized training, either a BA or MBA?
Like I said above, right now I only have a Bachelor's degree. However, I have also passed the PHR exam (Professional in Human Resources) which alot of companies prefer you to have but it is not required by most.
Having higher credentials will put you a step above the others in the job pool. However, I would suggest that you try to get some work experience before you go get your master's degree.
What are your typical responsibilities?
HR covers a broad range of things, depending on your title and your specific job description, your job duties will vary quite a bit. Try looking at
www.shrm.org for some general ideas.
What are some pros/cons of the job?
Again, these will vary depending on what area of HR you work in. For me, I love the hiring process and interviewing applicants. Plus I also get to plan all of the fun employee gatherings at my job (however, this isn't just an HR duty...).
The cons are pretty evident in this economy... having to make the decisions to reduce our workforce and being the one to break the news to the employee. It is never fun, and I don't think it will ever be something I get used to...
Anyhow, good luck in whatever path you decide to take and let me know if I can help you at all!
