Dear Customer,                                
Thanks for joining and trusting us, much appreciated!

We would like to inform you that if an employee lodges a complaint against the employer, due to non-renewal of the insurance, the employer must provide proof that the worker's complaint is not correct. The employer may also comply with what was stipulated in article 6 of the Labor Code, which confirms that he will not adhere to any claim regarding any right after a year on the date of termination of the contract. The judge may accept this or reject it.
Here is the text of UAE labor law that is related to your inquiry:
Article 6 
Without prejudice to the rules provided for under this Law concerning collective labour disputes, if the employer, the worker or any beneficiary thereof disputes any of the rights provided for any of them under this Law, he shall file an application to the competent Labour Department, which shall summon both parties and take whatever action it deems necessary to settle the dispute amicably.
If no such amicable settlement is reached, the said Department shall, within two weeks from the date of application, refer the dispute to the competent court under a memorandum containing a summary of the dispute, the arguments of both parties, and the Department’s comments. The court shall, within three days from date of receiving the application, fix a hearing date and notify the parties accordingly. The court may summon a representative of the Labour Department to explain the content of the memorandum submitted by it.
In all cases, no claim for any of the rights provided for in this Law shall be heard if brought to court after the lapse of one year from the date of accrual, nor shall any claim be admitted if the procedures stated in this Article are not complied with.
