Is an Oklahoma employer required to pay employees using FMLA leave?

Unpaid leave

Is my employer required to pay me when I take FMLA leave?

The FMLA only requires unpaid leave. However, the law permits an employee to elect, or the employer to require the employee, to use accrued paid vacation leave, paid sick or family leave for some or all of the FMLA leave period. An employee must follow the employer’s normal leave rules in order to substitute paid leave. When paid leave is used for an FMLA-covered reason, the leave is FMLA-protected.
