All perfect praise be to Allah, The Lord of The Worlds, and may His blessings and peace be upon our Prophet Mohammad and upon all his family and companions.
Allah, The Almighty, Has Specified eight channels for the disbursement of Zakah, as indicated in the following verse: " The voluntary almsgivings are only for the poor and the needy, and those who work with them, and those whose hearts are to be reconciled, and for slaves, and for the debtors, for the way of God, and for the traveller - a duty imposed by God. And God is Knower, Wise. " {At-Tawbah/60}.
Islam has made Zakah a fixed right for the poor and the needy as well as the rest of those entitled to it. Allah, The Almighty, Said: "And those in whose wealth is a recognised right." {Al-Ma`arij/24}.
Moreover, it isn`t permissible to give Zakah to people not entitled to it; whereas, the needy (Miskeen) are amongst those entitled to receive it. By definition, (Miskeen) is, for instance, someone who needs ten JDs but has seven. If the income of the employees referred to in the above question doesn`t cover their needs, then the term (Miskeen) applies to them, and so it is permissible to give them from the Zakah funds; however, it is better that you authorize someone else to deliver that Zakah in order to avoid suspicion. And Allah Knows Best.
