Ray Correio has put out a great article on the concept of "vocational apportionment". This is a master class on the concept and a must read!
The concept of “vocational apportionment” as currently formulated and applied by vocational experts in cases where there is substantial medical evidence of apportionment is inconsistent with and contrary to the Court of Appeal’s Decision in Acme Steel v. Workers’ Comp. Appeals Bd. (2013) 218 Cal.App.4th 1137; 78 Cal. Comp. Cases 751 as well as other recent decisions from the Court of Appeal.
