Is money earned by a mother who works as a nurse and is absent from her work without permission or necessity, then spends it on her family, considered illicit money, and is her work considered cooperation in sin?

An employee must adhere to the full working hours and is not permitted to shorten them except as allowed by regulations. An employee’s lateness or early departure does not forfeit the entire salary; rather, it forfeits only the portion corresponding to the breach of working hours. It is permissible to benefit from the mother's money even if she breached her work hours without valid permission. The fact that female students live far from their homes has no bearing on the ruling concerning the mother's work.
