Is the president entitled to dismiss an employee who is negligent in his work without warning, even if the employee's circumstances are difficult and he is in urgent need of the job?

Terminating a rental contract is not an absolute injustice; rather, it depends on the terms of the contract and the circumstances of the termination. If the rental period is specified, both parties are obligated to fulfill it unless there is a legitimate excuse, such as the worker's illness affecting their performance. If the questioner fell short in her work due to her incapacitation, this is an excuse for the employer to terminate the contract. Dismissal may or may not be unjust, and the reference for this is the terms of the contract and the reasons for dismissal. The issue of favoritism and consideration of human circumstances differs from the rulings on rental contracts; these fall under the categories of righteousness and benevolence. No one can cut off sustenance that Allah has ordained, for Allah is the Provider. Injustice and oppression without right are forbidden and carry a severe punishment. The supplication of the oppressed is answered, but the questioner's supplication for herself is more beneficial than her supplication against those who wronged her.
