Is money earned considered unlawful if an employee spends most of the working hours sitting idle without working, engaging in personal activities such as using the phone or studying, and is using work tools for personal purposes considered unlawful?

The employee must adhere to work timings and perform the tasks assigned to him with honesty and sincerity, so that his earnings may be good and his liability cleared. If the employee spends time without work due to a lack of tasks, this does not affect the permissibility of his salary. As for using office tools for personal use that incur a cost to the employer, it is not permissible except with the permission of the official and within the limits of need, and it is better to avoid it.
