My employer gave me termination letter but still...

We would like to inform you that referring to the Kuwaiti Labor Law and regarding the termination without reason or legal justification, it is considered an arbitrary dismissal that requires the employer to pay compensation to the worker
So the worker has gratuity if he spent at the employer's service a period of not less than one year, and if the service period was less than a year, then you can only compensate for the arbitrary dismissal allowance
For termination and cancellation, below article states:
Article (44)
In the event where the term of the work contract is not specified, both parties shall have the right to terminate the same by means of a notice to the other party as follows:
a- Three months prior to the termination of the contract for the workers earning a monthly remuneration.
b- One month prior to the termination of the contract for other workers.
In the event where the party wishing to terminate the contract does not abide by the period of notice, he shall be obliged to pay the other party a compensation for the notification period equal to the remuneration of the worker for the same period.
c- In the event where the notification of termination is issued by the employer, the worker shall have the right to be absent one day or 8 hours per week in order to search for other work. He shall also be entitled to his remuneration for the day or hours of absence.
The worker shall decide on the day or hours of absence and shall notify the employer at least one day prior to such absence.
Article (47)
In the event where the term of the work contract is specified and the contract was unrightfully terminated by either party, the terminating party shall compensate the other party for damage provided that the amount of the compensation shall not exceed the remuneration of the worker for the remaining period of the contract The damage suffered by the parties shall be determined according to trade custom, the nature of the work, the duration of the contract and in general all considerations that may have an effect on the damage with regard to its existence and extent. All debts due to the other party shall be deducted from the value of the compensation
Therefore, you may go to the labour office and submit a complaint against the employer and claim all labor rights in addition to the gratuity and compensation for arbitrary dismissal
