It is allowed to extend my days of duty.. My last...

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

We would like to inform you that If the contract of employment has expired, the contract can't be extended without the consent of the parties. If the worker and the employer agree to the extension without signing the contract, the previous contract of employment has now become an indefinite employment contract which ends only by informing the other party of the desire to terminate the employment contract at least one month before termination.
Here is the text of the UAE Labor Law, concerning your inquiry:
Article 39

 An employment contract shall, from its inception, be considered as an indefinite term contract if and only if it:

1. Is not written.
2. Is concluded for an unspecified period.
3. Was originally written and concluded for a definite term but both parties, without a written agreement between them, continued to perform it after its expiry; or
4. Was originally concluded for the execution of a specific work that had no specific duration or that is recurrent by nature, but the contract continued after completion of that specific work.
