Having a master's doesn't always pay off.Joe Raedle/Getty ImagesFor some jobs, having a master's degree is a must.
But while attending school for additional year or two after acquiring your bachelor's degree may qualify you for a particular job (and cost you a pretty penny), it doesn't always guarantee that you'll get paid the big bucks for it.
In fact, according to the latest data from the US Bureau of Labor Statistics, there are a number of occupations that require a master's degree and pay less than the median annual salary of the average master's degree holder, which is around $70,000 a year.
Here are some of the lowest-paying:
