Start with the scene, not the argument.

If you're a postal worker in Chicago with a lumbar fracture after a commercial truck hit you on your route, and the comp carrier is now acting like your surgery is somehow "not supported," the fight is about evidence before it's about medicine.

And some of that evidence disappears fast.

Photograph the boring stuff first

Most people take one or two injury photos and stop. That's not enough.

Photograph the exact place where the truck hit you. The curb. The crosswalk paint. The potholes. The loading zone signs. The alley entrance. The parked vehicles that blocked sightlines. If this happened in the Loop, Little Village, Jefferson Park, Bronzeville, wherever, lock down the location like you're documenting a crime scene.

Take wide shots first.

Then medium shots.

Then close-ups.

If there's blood on mail, torn satchel straps, a broken scanner holster, bent cart wheels, skid marks, shattered mirror plastic, or your uniform ripped at the hip or back, photograph all of it before anyone "cleans things up."

Do not wash or throw out the uniform, boots, gloves, or bag. Bag them. Label the date.

The adjuster will happily call it a "soft tissue complaint" if the visuals are gone.

Your phone is evidence too

Save your own phone records now, not next month.

That means screenshots of your call log, texts, voicemails, location history, route messages, supervisor contacts, and any photo metadata showing when and where images were taken. Export what you can to cloud storage and email it to yourself.

Why? Because phone carriers don't keep every detail forever, and your device can get replaced, wiped, or damaged. If you called a supervisor from the scene, texted "I can't move," or got route instructions right before the crash, that timing matters.

Also save any fitness or health app data showing steps, motion, impact, or sudden inactivity. That sounds small. It isn't.

Witnesses vanish in Chicago faster than you think

A witness who says, "Yeah, I saw the truck cut too close," can become unreachable in a week.

People work odd hours. They move. They ignore unknown numbers. Store employees transfer. Delivery drivers are back in Cicero, Bedford Park, or Joliet by the next morning.

Get names, cell numbers, emails, employer names, truck numbers, and plate numbers immediately if you can. If you were taken out by CFD ambulance, ask a family member or coworker to go back and look for nearby businesses with cameras and workers who saw it.

One short list is enough:

• Truck company name, USDOT number if visible, trailer number, plate, witness names, nearby business cameras, your supervisor's name, ambulance run number, and the police report number

That list saves cases.

Dashcam footage is not "theirs" to sit on forever

Commercial trucks in Chicago often have dashcams, inward-facing cameras, telematics, hard braking data, and GPS route logs. The problem is a lot of those systems overwrite footage quickly. Same with security cameras from gas stations, condo buildings, loading docks, and corner stores.

You do not have some magic instant right to walk in and demand the video.

But you absolutely can demand that it be preserved.

That needs to happen fast. A written preservation demand to the trucking company, its insurer, any nearby business, and anyone else with video can stop the usual "sorry, it was overwritten" nonsense. If this happened near a warehouse corridor on Pulaski, a loading dock off Western, or a tight alley in River North, assume multiple cameras caught something and assume most owners will not save it unless pushed.

And yes, USPS vehicles and scanners may have their own data trail too. Route logs, scanner timestamps, and internal incident reporting can help pin down where you were and when.

Get the police report, but don't worship it

If CPD responded, get the crash report as soon as it's available. In Chicago, that report may take a little time to show up, especially if the scene was chaotic or you were transported out fast.

Check it for basic errors.

Wrong location.

Wrong lane.

Wrong vehicle type.

Wrong employer.

Missing witness.

Those mistakes happen all the time, especially when the injured worker is already in the ambulance on the way to Stroger, Northwestern, Illinois Masonic, or University of Chicago.

The police report matters because insurers use it as a shortcut. But it is not the whole case. A bad report can be corrected or countered with photos, records, witness statements, route data, and medical notes.

The surgery denial fight is really a record fight

Here's what most people don't realize: when the comp carrier delays lumbar surgery, it usually starts by pretending the medical story is fuzzy.

So make it less fuzzy.

Save every ER record, discharge instruction, imaging order, MRI report, work status note, and doctor recommendation. If a physician said the fracture is consistent with truck impact trauma, that wording matters. If the pain shot down your leg the same day, that timing matters. If you told the first doctor you were struck while delivering mail near an intersection and that exact mechanism is in the chart, that matters a lot.

The first chart often hits harder than the fifth.

That's true in Chicago and it's true in places like Peoria and Rockford too, where aging industrial infrastructure and rougher workplace conditions produce the same ugly pattern: a serious injury happens, then the paperwork starts sanding off the edges until the insurer acts like no one can really tell what happened.

You can tell.

But only if you preserve it before someone else controls the file.
