Is it permissible to accept compensation for dismissal from work in non-Muslim countries, knowing that the law guarantees it? And are the interests added to delayed salaries considered usury that must be disposed of?

The employee may demand from the employer the wages for the six months he worked without any increase, and he is entitled to recover litigation costs, such as attorney's fees. Regarding compensation for termination: If the contract was ongoing and the employee was able to work after his injury, the company is not permitted to terminate him, and it is obligated to pay his wages until the end of the contract. However, if he is unable to work, the company may terminate the contract and is not obligated to pay his wages for the remaining period. Therefore, the employee is entitled to compensation equivalent to the wages for the remaining period of the contract if he is entitled to them, and he must return the rest. He is not entitled to any compensation if he is not entitled to the wages for the remaining period.
