I presume you're talking about receiving temporary total disability benefits. That depends on a whole lot of facts that are unknown. First and foremost, whether your employer and their WC carrier are accepting liability for your injury. Second, whether a doctor has legitimately certified you as unable to work. Third, whether the claim needs to be investigated.
You don't just tell your employer "I hurt my leg," head home, and wait for the checks to start rolling in.
If you have questions about the status of your WC claim, your very best option is to contact your employer and ask them.
