Is it permissible for an employee who sees negligence from his colleagues to report it to the manager?

Question:
He says: Honorable Shaykh, may Allah grant you success, if I see some of the employees… hmm? He says: If I see some of the employees being negligent in their attendance and departure, should I report them to the person in charge, even though that causes enmity between me and them, or should I remain silent because of that?

Answer:
Advise them. Advise them and encourage them to fulfill their duty. This is what is obligatory for you. As for informing the person in charge, that person is the one who looks for them, the one who tracks them, and there are supervisors; this is not entrusted to you, but you are required to give advice.
