Answer
No, we do not contact your employer.
We work separately from your employer, and don't affect your paycheck deposits. When you cash out, the money (plus your tip) is automatically deducted from your bank account on payday, after your payroll comes in.
Additional notes
Introduce us to your employer, so that we can work directly with them to allow you to access your whole paycheck. Email us on perks@earnin.com to learn more.
