Most states have laws that require employers to pay employees their wages with some minimum frequency—usually either twice a month (semi-monthly) or every other week (bi-weekly)—and some states require weekly or monthly payment of wages.

These laws are known as payday laws and also dictate when an employee who has been fired/terminated or quit must be paid their final paycheck—in some states, immediately; in some states within a certain number of days; and in some states on the next regularly-scheduled payday.

Payday laws vary from state to state and are usually included in a state’s statutes—often in the labor code or other statutes governing employer-employee relations.

In Oklahoma, the regulation regarding the payment of wages is outlined in the Oklahoma Statutes, Title 40, which covers labor laws. Employers are required to pay employees at least twice each month, unless otherwise specified by the Department of Labor. Specifically, the law mandates that labor be paid for in lawful money of the United States by the 15th and the last day of each month. When it comes to the final paycheck for an employee who has been terminated or has quit, Oklahoma law requires that the final wages be paid by the next regular payday. The exact timing can depend on whether the employee was fired or quit. If an employee is fired, the employer must provide the final paycheck by the next regular payday, whereas if an employee quits, the final paycheck is due by the next regular payday following the resignation. It's important for employers to adhere to these regulations to avoid penalties and legal issues.
