While a termination letter is considered good practice, there are no federal or Arizona state laws that require it. In fact, because Arizona is an “at-will” employment state, an employer is under no obligation to provide any reasoning for terminating an employee.
To quit, write a simple letter addressed to your supervisor that says nothing more than you are resigning, and which day will be your last. Don't mention your reasons or future plans, no complaints, just your resignation and effective date.
Employment-at-will applies to all employees and employers in Arizona. With employment-at-will, an employee does not guarantee that he will stay on the job for any amount of time. An employee can quit at any time for any reason even if the employer needs the employee to be at work.
Like many other states, Arizona is an “at-will” employment state. This generally means that employers can terminate employees at any time for any reason—or even no reason at all—without incurring legal liability. Likewise, an employee can quit at any time without providing a reason or advanced notice.

Arizona law provides that an employer may terminate an employee at any time.

(A.R.S. § 23-1501).
If you don't serve your notice, you'll be in breach of contract. However, they can't do anything about it without taking you to court to try and recoup ``damages'' caused by you not serving your notice. Unless you're very important, it's unlikely they'd be able to prove any damages in court.
If you change your mind about resigning, tell your employer straight away. Your employer does not have to accept your request to withdraw your resignation. However, they should give it serious consideration, especially if: you very quickly changed your mind about resigning.
The employee therefore has no right to withdraw the resignation without the agreement of the other party – the employer. In other words, the employee has no legal right which entitles him to unilaterally withdraw his resignation. The same principle applies to other issues revolving around the employment contract.
