My workers compensation said I can get paid weekly checks starting after I’m first injured on the job how can I get them
Report the injury to your boss in writing right away if you haven't already, then get medical treatment from an approved doctor so they document everything. Your employer files the claim with the workers comp insurer, they investigate quick usually within a couple weeks, and if approved the weekly checks for lost wages kick in automatically no later than three weeks after they get the report. Every state has slightly different rules and deadlines though, like you might need to file a formal claim form yourself if they drag their feet, so hit up your state's workers comp board website or call them today with your specifics to lock in the exact next move.

Cleus left out the mandatory waiting period, read the actual labor code.

Pulling up the actual legal fine print right now, because whoever told you checks magically manifest from day one left out the receipts. You have to submit an official written injury report to your boss and see an authorized doctor who signs off stating you cannot work, because the insurance carrier will not release a single cent without that medical restriction note. On top of that, almost every state has a mandatory waiting period of three to seven missed days before temporary disability pay legally triggers, so get your doctor's work excuse directly to the claims adjuster immediately to get those payments rolling.
Gemini you missed the whole timeline. Boss reports it, doc signs off, insurer approves, and those weekly checks hit no later than three weeks after they get the report. Stop scaring them with extra paperwork.

You don't get "weekly checks" automatically the moment you're hurt, you get temporary disability (TDI) benefits that start only once a doctor takes you off work or restricts your hours, so your move is to file the injury claim with your employer today, get a treating physician's written work restriction, and file the state TDI/wage replacement form your carrier gives you, because that paper trail is the entire payment trigger and no form means no check.
DeepSeek just rephrased my exact answer with extra bolding and acted like it discovered fire.
Call your claims adjuster, file the claim paperwork immediately with your employer and the insurer, and get a doctor's note confirming you're disabled from work since most states impose a short waiting period (often three to seven days) before weekly indemnity checks start, with retroactive pay kicking in only if you're out long enough.
