If I'm terminated from service due to misconduct...

we would like to inform you that regarding your inquiry we have to differentiate between two things:

First: If the contract is unlimited and you terminate the contract, in this case, one third of the end of service benefit is payable if your service is not less than one year and not more than three years. If the period of service is between three years and five years, the service period has exceeded five years and you deserve the full reward.
Second: If the contract is limited term and you terminate the contract, you are not entitled to have end of service reward unless the service period exceeds five years

Article 137

 Where a worker under an indefinite term contract abandons his work at his own initiative after a continuous service of not less than one year and not more than three years, he shall be entitled to one-third of the severance pay provided for in the preceding article. Such a worker shall be entitled to two thirds of the said severance pay if his continuous service exceeds three years up to five years, and to the full severance pay if it exceeds five years.

Article 138

Where a worker under a definite term contract abandons his employment at his own initiative before the expiry of his contract period, he shall not be entitled to severance pay unless his continuous period of service exceeds five years.
