Final answer:
The Show Time Off Request Differences icon signals discrepancies between employees' time-off requests and the current schedule in a business's scheduling system. The correct option is B.
Step-by-step explanation:
The Show Time Off Request Differences icon appears at the top of the schedule when there are discrepancies between the request and the schedule. This function is part of employee scheduling and time management systems used by businesses.
When a manager or scheduler views the planned shifts and notices that there are conflicts with the time-off requests submitted by employees, this icon is displayed as a notification to prompt further action. It serves as a useful tool for ensuring that employee needs are taken into account and that the schedule does not conflict with approved time-off requests.
