Which CTA code represents a situation where an employee is sick?

The correct code that represents a situation where an employee is sick is 10-61. This coding system is used within the Chicago Transit Authority to standardize communication, particularly concerning employee statuses and conditions. Each code is assigned a specific meaning to facilitate quick and effective communication among staff and personnel.

In this context, 10-61 signifies that an employee is reporting an illness, which is crucial for ensuring proper coverage and handling of work responsibilities. Accurate reporting allows the organization to respond appropriately, such as reallocating tasks or addressing staffing needs.

Other codes in the provided options represent different scenarios and do not pertain to illness. Knowing these distinctions is essential for effectively interpreting and using the CTA's communication codes.
