What does "protecting injured workers" actually look like in real cases?

I keep seeing that phrase everywhere when I'm researching what to do after my accident at a landscaping job near Rhinebeck – I fell off a ladder and broke my ankle in two places, and the insurance company already tried to say I wasn't following safety rules so they might deny me. But what I'm really wondering is, when a law firm says they focus on Protecting Injured Workers in Rhinebeck NY, what does that mean day to day? Like, are they just filing paperwork faster, or do they actually push back when the employer lies about what happened? I read somewhere that lawyers can depose witnesses and force the company to hand over safety records, but is that something that happens in normal workers comp cases or only in really big lawsuits? I'm trying to figure out if hiring someone would actually change the outcome or just add another layer of stress. If anyone has been through a contested claim and seen what a good attorney does behind the scenes, I'd love to hear the real story.
