What is the ruling on my remaining at work with no tasks, browsing the internet, and leaving before the official end of working hours, knowing that I record the actual time of my arrival and departure in the registers?

The employee is a private hire by their employer, whose benefit is estimated by time, and who is entitled to wages by dedicating themselves to work, whether work is available or not. Therefore, working hours are owned by the employer, and it is obligatory to adhere to attendance and departure during them. It is not permissible to leave before the end of working hours except with permission from an authorized person. Moreover, an employee’s writing of their actual departure time does not exempt them from their contractual obligation. As for browsing the internet or newspapers, or engaging in personal work during free time that does not affect work, there is no harm in it, but seeking permission from the employer is preferable.
