To what extent is the incentive system permissible that is divided into three sections (commitment to attendance, behaviors, company production), and in which deductions are made from incentives based on days of absence, even if the absence is due to a compelling excuse?

The employee and the company must adhere to the terms of the concluded contract unless they violate Sharia. If the worker neglects his duties and is absent from work, the employer may penalize him by deducting his wage commensurate with his negligence, without injustice. As for the matter of excuses when an employee is absent, it is governed by Sharia, custom, and the contract. Among the legitimate excuses are Eid days, and among the customary excuses are known holiday periods, and the employee is entitled to his wage on these days. The same applies to days of sickness and the like if custom dictates so; otherwise, the company may deduct wages for the period of absence. As for incentives, they are a grant that the company may dispose of according to its terms.
