Is it permissible to take six months' salary based on labor law without the employer's knowledge after arbitrary dismissal?

We have not seen the labor law in question nor the concluded contract, and therefore we cannot rule on the matter until we examine them. However, there are possibilities:

1. If the contract stipulates a 6-month notice period before termination, then you have the right to demand it. If refused, you may claim your right through legal means or discreetly.

2. If the contract does not stipulate the notice period, but labor law obliges companies to provide it (a recognized custom), then the ruling is as above.

3. If the notice period is not stipulated in the contract and is not a recognized custom, then you are not entitled to take the man's money without his consent. He has the right to terminate your employment unless the contract had a specified duration and he did not reserve the right to terminate whenever he wished.
