Muslims need to be forerunners in justice and kindness when dealing with those in our employ.
It is We (Allah) Who divide among them their livelihood in the life of this world, and We exalt some of them above others in rank, so that some of them may command work from the others. (Qur’aan 43:32) Allah made some people rich, others poor. The poor are dependent on the rich for their bread, and the rich on the poor for labour.
The Employer
Possession of wealth is by Allah’s permission: Allah enlarges livelihood for whom He wills and reduces it for whom He wills. (Qur’aan 13:26) What you possess is a trust. The Qur'aan states: do not consume your property among yourselves wrongfully, but let their be trade by mutual consent, and do not kill yourselves. Believers are warned against exploitation. Do not kill yourselves refers to the outcome of exploitation: it starts a cycle of hatred which rebounds on the oppressors. Exploitation is self-destruction.
Dignity of Employee
(They are) your brethren whom Allah has placed in your custody. Let him who has been made custodian of his brother by Allah feed him from what he himself eats, clothe him out of what he clothes himself, and impose not on him work that will overcome him. (Bukhari) Employees are your human brothers. Pay them enough so they can maintain themselves with dignity. Do not impose on them so much work, or so long working hours that is overbearing.
The Prophet (sallallahu alaihi wa sallam) said: One who mistreats those under him will not enter paradise. (Tirmidi) Good treatment of those under you brings fortune, whilst bad treatment brings misfortune. (Abu Dawood)
Wages
Man is entitled to no more than what he works for. (Qur’aan 53:39) The minimum wage in Islam should be sufficient to meet his basic essentials. Anas (radhiallahu anhu) said: the Prophet never paid a low wage to any person. (Bukhari)
Ali (radhiallahu anhu) said: ‘Allah has made it obligatory on the rich to meet the economic needs of the poor up to the extent of their absolute necessities. If they are hungry or naked or involved in other financial difficulties, it will be merely because the rich are not doing their duty.’ (Muhalla)
