No, EarnIn does not contact your employer.
When you use Cash Out, your money (plus any Lighting Speed fees and optional tips) is automatically deducted from your bank account on payday, after your employer processes payroll.
Early Pay and EarnIn Card
If you sign up for Early Pay or EarnIn Card, your direct deposit is routed through your EarnIn deposit account (banking Services are provided by Evolve Bank & Trust, Member FDIC).
This means you’ll have to update your direct deposit information through your employer’s payroll portal, however EarnIn does not contact your employer before or after this process.
