We would like to inform you that Upon termination of the service of the worker the employer shall at his cost return him to the place from where he has recruited him at the commencement of the engagement or to any place agreed upon between the parties.
In addition to any sums to which the worker is entitled to upon the expiry of his service, the employer shall pay the end of service gratuity to the worker who has completed employment of one year or more. This gratuity shall be agreed upon by the two parties, provided that it is not less than a three-week wage for every year of employment. The worker shall be entitled to gratuity for the fractions of the year in proportion to the duration of employment.
If the employer refused to give these amounts, then you can file a complaint in the labor office against the employer.
