What should I do?

Before I hung my shingle and started working for myself, I spent 20 years sitting on my butt as a paralegal in law firms for both the plaintiff and the defense over the years. :-D The last guy I worked for (for nearly 8 years) was one of the best Labor Law lawyers in the entire state of California.

Start here: http://www.lni.wa.gov/ClaimsIns/Rules/WorkersComp/default.asp These are the laws governing work-related injuries in the state of Washington.

You have obligations not only to yourself but to your employer; he also owes you certain duties that are undeniable in a court of law. A failure on either's part to do what you're supposed to do under these circumstances can and WILL come back to bite both of you on the backside.

Don't wait to see a doctor! The longer you do, the more likely it is that the insurance companies covering your employer and the lady who hit you will deny your claim outright because it wasn't reported in a timely fashion (and that in itself can hurt your credibility as a witness in court). Go to the Emergency Room or Urgent Care or SOMEWHERE and get checked out immediately; be honest with the doctor about everything that hurts (or might hurt in a day or two), go to all of your follow up appointments, get x-rays, and do everything you're instructed to do. If you have to take a few days off from work to recover, DO IT. Your first few days of missed work may have to come out of your vacation or sick time but anything beyond that will probably be covered by state disability. (Your boss should fill out any papers you need for that too -- do it yourself if they don't -- and be just as diligent with follow ups on it or you'll look like a flake in court.)

If it seems like you might suffer adverse affects at work like you seem to be so worried about, keep a daily log / diary noting everything you're going through -- pain, inability to sleep, your boss hovering over you, not offering you restricted or light duty, etc., etc., because if this matter ever ends up in court, it's going to be a few years down the road and your memory will NOT be as crystal clear as it is right now. That little book is going to save your *** (and possibly your job) and will be some of the best documentary evidence of your injuries and everything you've endured along the way. And it should say a lot more than just "August 2, 2014, 9:47 a.m. -- my back hurts and my boss is a dick."

Though work-related injuries' settlements are calculated differently than civil [non-work] matters, also keep track of the dates and mileage back and forth to doctors' appointments, physical therapy, and anywhere else your employer or doctor may send you too because you can get reimbursed for that down the road ... but NOT if you don't keep track of it all.

If you do suffer adverse effects at your job because of your accident, keep in mind that everything you've ever done at work that wasn't perfect can and may be brought up in court to discredit you. Let's say you're habitually late on Monday mornings, or took a 17-minute break on February 4, 2008 instead of the 15 minutes you're supposed to take. Your boss has a personnel file about you, trust me ... and it's because of this kind of stuff that he does so. He's already got his "log" about you so you need to have your own. What's important to remember is that it won't be your boss per se trying to discredit you -- his or the other driver's insurer is, and it's only because they'll be trying anything and everything they can to try to limit the amount of money that they're going to have to pay you later.

You have an adventure ahead of you YG2.0. I can't promise that it will be fun but it will surely teach you a lot about workers' compensation and the way that seemingly innocent things can come back to haunt you later. I wish you luck sweetie!! Hit me up if I can help you out.
