Interchange of Labor - Differences between NCCI & WCIRB

We are excited to review the rules for Workers compensation in relation to the interchange of labor between NCCI states the WCIRB (California). There are some similarities between the two, but they also have their differences. We will explain some of the basic rules for both the NCCI and WCIRB and then so through some examples that illustrate these differences. Inevitably when talking about interchange of labor, the topic of division of payroll will come up so we will also explore the rules associated with dividing wages between certain classifications. Our goal is to make clear these rules and have some interaction from the audience on what to do in certain situations.
