An employee is injured on Friday, January 10, 1992. The injury is reported to the supervisor by another employee on January 12, 1992. What is the employer's date of knowledge?

• A. 1-10-92, date of the injury
• B. 1-12-92, the date of knowledge
• C. 1-12-92, date of the injury
• D. 1-10-92 the date of knowledge

Answer: (B)

Date of knowledge is the date the employer first learns of the injury, not the date the injury occurred. In this scenario, the injury happened on January 10, but the supervisor first became aware of it on January 12 when another employee reported it. Therefore, the employer’s date of knowledge is January 12, 1992. This date matters for meeting notice requirements to the self-insurance plan or insurer. If knowledge had been obtained earlier, that earlier date would control; if later, it would push the notice deadline accordingly.
