From the Introduction to the Guide:
"This Guide is intended to simplify and answer questions about applications, eligibility, benefits and appeals in the unemployment insurance (UI) process, which in Massachusetts is operated by the Division of Unemployment Assistance (DUA). It contains citations to relevant employment law, regulations and case law as well as policies, practical information and exhibits found useful by those familiar with the system. Its aims are to assist advocates through the maze of regulation and policy and to provide advocates with the tools necessary to help unemployed workers obtain the UI to which they are legally entitled."
