She has given new meaning to a class-action lawsuit. Trina Thompson gave it the old college try, but couldn't find work. Now she thinks her sheepskin wasn't worth her time, and is suing her alma mater for her money back. The Monroe College grad wants the $70,000 she spent on tuition because she hasn't found gainful employment since earning her bachelor's degree in April, according to a suit filed in Bronx Supreme Court on July 24. The 27-year-old alleges the business-oriented Bronx school hasn't lived up to its end of the bargain, and has not done enough to find her a job.
