All Muslims should observe their duty toward Allah. This applies to the rulers and the ruled, the managers and employees, husbands and wives, parents and children, etc. Prophet Muhammad (peace and blessings be upon him) said, “All of you are guardians, and all of you are responsible for your wards and the things under your care. An imam [i.e. ruler] is the guardian of his subjects and is responsible for them, and a man is the guardian of his family and is responsible for them. A woman is the guardian of her husband’s house and is responsible for it. A servant is the guardian of his [or her] master’s belongings and is responsible for them. All of you are guardians, and all of you are responsible for your wards and the things under your care.”

The relationship among all people should be based on piety and cooperation for the good of the humanity. So, any Muslim should always be fearful of Allah and keen on doing what is good and avoiding what is bad.

The eminent Muslim scholar and da`iyah`Abdul Khaliq Hassan Ash-Shareef stated: The psychological aspect of the relation between the employee and his or her boss has to be considered. From such perspective, it is not uncommon that an employee searches for and then over stresses minor defects in the personality of his or her boss.

Moreover, Samy Ahmed Mohamed, an Islamic researcher at IslamOnline.net, added: The relationship between a boss and an employee should be based on cooperation and piety. While an employee is required to observe his or her duty toward Allah by doing his or her best to excel at work, a supervisor is also asked to do the same. He or she should practice leadership honestly and professionally.
If a Muslim employee encounters a mistake made by his or her boss, he or she is advised to wisely address the issue with the boss. If the boss insists on doing the mistake or misusing his or her authority, then the employee has the right to address the issue with those in charge of this boss. In this case, the employee should honestly report the case with the intention of protecting the interests of the workplace.
May Allah help us all perceive truth and follow it and help us perceive falseness and shun it.
