In the injury scenario where the employee was injured on Friday, January 10, 2008, reported the injury on January 12, and filed a claim form on January 15, 2008, what is the employer's date of knowledge for Labor Code section 5402?

• A. January 12, 2008
• B. January 10, 2008
• C. January 15, 2008
• D. January 16, 2008

Answer: (A)

Date of knowledge is the date the employer actually learns of the injury, not when the injury occurred or when a claim is filed. In this scenario, the employee reported the injury on January 12, so the employer becomes aware on that date. The injury occurred on January 10, and the claim was filed later, on January 15, but those dates do not set the employer’s knowledge. Therefore, the employer’s date of knowledge is January 12. This date matters because it triggers the timing for certain obligations and deadlines under Labor Code section 5402.
