Taxpayer rec'd letter from his employer

RE: 7,830 paid to CVWD in Calendar Year 2022 under FMLA Leave

Letter states W-2 Form for 2022 reports full wages paid including time off related to Paid Family Leave. Employer suggests giving letter to his tax preparer to avoid over taxation. That implies he would be getting taxed on the money paid by the employer and on the money he gave over to the employer.
