In "The Insurance Professional's Practical Guide to Workers' Compensation," Chris Boggs addresses in clear, jargon-free English many of the concepts, policies and practices in workers compensation that brokers, risk advisors, and corporate risk managers need to know. The chapters, such as on which injuries and which workers are covered, free the reader from having to wade through dense legal and regulatory treatises. I don't know of any other writer in workers compensation who is as careful and articulate as Boggs in explaining to non-lawyers legal aspects of workers compensation. If you need to use the book as little as one time a year, get it, because you'll probably need it much more often.
