Step-by-step explanation:
The company XYZ is using a flexible working hours policy, also known as flextime. Flextime allows employees to decide when they will work their additional hours, as long as they are present during the core hours of 10 am to 3 pm. This policy gives employees the flexibility to accommodate personal commitments, such as work-life balance or appointments, while still fulfilling their work responsibilities. For example, an employee may choose to start work earlier at 7 am and finish at 3 pm to have the afternoon free.
