Is it permissible to take a paid sick leave from an insurance company while continuing to work and receive another salary, knowing that the doctor is aware of this?

The general principle in companies is that a private employee should not receive two salaries during their illness and leave, except in exceptional cases and under specific conditions, which are: 1. That your work during sick leave does not hinder recovery. The assessment of this is up to a trusted doctor. 2. That the insurance paying the compensatory salary is cooperative. If it is commercial, then it is not permissible to benefit from it except to the extent that was paid into it. 3. That the doctor is trustworthy and honest, not granting sick leave except to those who deserve it. 4. That your illness does not affect your contractual production level; because the basis of the contract is the worker's well-being, and if their production falls below the general average, they must clarify their situation to the company. 5. Informing the company about the matter, as it is responsible for evaluating your job production level, your health insurance, and confirming your entitlement to leave and financial compensation.

If these conditions are met, there is no harm in the employee receiving both salaries together, as the reason for each salary is independent of the other.
