In what year was MGL c149 s148, as it is written today, signed into legislation?

I need to know when MGL 149 s148, a.k.a. MA Wage Payment Act, as it exists today, was approved as a law. I've traced the law back to the early 1900s, but the wording has changed slightly over the years. I have a small claims case amendment pending. I was discharged May 2008. I was not paid my final wages on the day of dismissal from a college. My employer says c149 s148 doesn't apply because they claims it was enacted as law in July 2008 and doesn't apply to my situation although the statement "any employee discharged from such employment shall be paid in full on the day of discharge" has been on the books since the early 1900s, but not preceded by the exact wording that exists today. Looking for some insight.
