It is NOT voluntary Senior dmattox, all Electricians as employees of C-10's, who use tools, connececting 100va or more. MANDITORY!
As for enforcement, I have it from word on high, from the Consultant hired to impliment the program, that "Insurablity" will be the enforcement method, i.e. No Certified Employees, no workmens comp, NO WORK! (The DIR also sets rules for the workmens comp' companies. And has a new "Enforcement dept".http://www.dir.ca.gov/dlse/dlse.html )
