Terminating an employment contract by employee before one year without fines or ban

Dear sir,

This question is for UAE lawyers.

My employer has written in our limited contract that I cannot work in any competing business in the UAE for one year if the contract is terminated by me or him and also 1 more line that says I have to pay 3000 AED as training fees if the contract is terminated before a year of the contract (I haven't received any training whatsoever).

Is there any way I can terminate the contract before 1 year without any fines or ban?

(The reason for terminating the contract is overtime for 16-hour duty with very poor living conditions).

Kindly answer me!
