Does an employee's taking extra copies of work-related booklets and calendars for his family constitute ghulool (unlawful appropriation), and what should he do with the remaining quantities?

An employee is entrusted with what is under their authority and must adhere to the instructions given regarding the distribution and division of what they are responsible for. They should not overstep what they have been explicitly or customarily permitted to do, because customary permission is equivalent to verbal permission. Accordingly, it is not permissible to dispose of books except as explicitly or customarily permitted. One can refer back to the employer to seek permission for anything that is unclear. For an employee to take copies for themselves, explicit or customary permission is required.
