Ruling on employees leaving off the congregational prayer

Question:
If a person is a supervisor at his workplace and does not perform the prayer with the congregation, and some of those under his administration also do not perform the prayer, and they have been advised to perform it, but they refused on the excuse that they perform it when they leave work, what is the ruling on that?

Answer:
The one who has a supervisor who does not pray with the congregation, or some of his colleagues, he and his brothers, the employees, should strive to pray in congregation and not imitate their supervisor in that. They should pray in congregation and strive in that. The supervisor should be advised. If that benefits him, well and good; otherwise, his case should be reported to those above him, to the head of the organization, or to whoever the questioner believes has the ability to forbid this evil. He should not neglect it, even if he does not sign his name, or even if he writes, "I am the one advising that so-and-so, the supervisor, or so-and-so, the manager, does not pray with the congregation," to the ruler of his land, to the judge of the court, to the minister of the interior, or the like, to the other scholars. There is no objection to this from the perspective of cooperating in righteousness and piety. The calamity is silence and the lack of cooperation. This is the calamity that increases evil and decreases good. But if Allah facilitates cooperation among the Muslims, this one writes, and this one forbids it verbally in a good manner, and this one contacts someone he hopes will be of benefit. When cooperation is achieved, much good generally results.
