Good Sir/madam.. please sir what are the step I...

It should be noted that after reviewing your inquiry and legal scrutiny we would like to inform you that if the employer does not pay the salary due to you in a regular manner, it is a violation to the contract and the labor law, and you can file a complaint and request to breach the contract because they are not pay your salary and request to join another employer 
According to the Federal Labor Law, the obligation of the employer to pay the employee's salary is one of the most important responsibilities that the work contract imposes on the employer. Violating this obligation gives the employer the legal right to terminate the employment contract and get all the rights, including the right to be transferred to another employer after the approval of the Interior Ministry and the Human Resources and resettlement.

As the UAE Labor Law states:

Article 121:

A worker may leave work without notice in one of the following cases:

1- If the employer violates his obligations before the worker in the articles stipulated in the contract or the law.

2- If the employer or his legal representative signs an assault on the worker.
