Most of us are not nurses or doctors or EMTs. That does not mean we could not join one of these professions -- if we were willing to put years into schooling, studying and gaining experience in the lines of work. It's also likely that you could, with years of focused study and training, become an architect or an engineer. None of these are particularly easy occupations to pursue, but with extended concentration on the subject matter and dedication to learning from books and then gathering experience, most of us could fill most of these jobs.
The same is true in law. If you have a love of law and a years-long dedication to learning the law and then applying it in your work life, you will at some point become an attorney, and then at some point later, become an experienced attorney well-versed in a particular area of practice. When you glance at the California Labor Code's sections on workers' compensation, you quickly grasp why it takes years to not only learn what the text says and means, but also how to apply it in order to help workers injured on the job.
The Labor Code is not light reading, including Division 4, Part 1, Chapter 1, where it begins an extended discussion of workers' compensation. Reading through the code, you can learn how the legal system defines employers and employees and under which conditions an employer is responsible for providing compensation to an injured worker.
It discusses workers' comp insurance, liability, self-insuring, medical examinations and medical issues, adjustments of claims, computations of benefits, independent contractors, medical and hospital treatment, compensation claims payments (including lump sum payments), direct payments, arbitration, hearings, findings, reconsiderations, reviews, retraining, rehabilitation and many, many other subjects.
Speak with an experienced workers' comp attorney before entering the system to fight for denied benefits. We have been for decades helping Coachella Valley workers fight insurers, employers, doctors and others who would deny them the medical care and wage replacement they are depending on.
