Is working in a government job under a system of one continuous work week (24 hours a day with a sleep period) followed by three weeks of rest, when the approved system is 15 days of work and 15 days of rest, considered unlawful (haram) or doubtful, knowing that this modification is illegal and may expose employees to accountability?

It is not permissible for employees to change the work system on their own without the approval of the employer, as this constitutes a breach of contract. Allah Almighty has commanded fulfilling contracts, and Muslims are bound by their conditions. Official working hours are the property of the employer, and an employee is not allowed to neglect them, even if they have no work to do. The mentioned punishment by the inspector indicates that the employer has not authorized or approved this action. Employees must cease this behavior, and the questioner must perform his work according to the agreement; he will not be harmed by the misguidance of others.
