How much does a bank teller at chase bank earn?

I work for chase as a Teller here in the Bronx, New York City. I just started 3 months ago. I earn $11.25/hr On top of my bi-weekly salary I can make more money through referrals. That's the process of sending a customer you were helping over to see one of Chase's personal bankers. If the customer you sent over does business with chase ie, signs on for a new credit card, takes out a loan, opens a new account, that's money in your pocket (between $5.00 and $7.50 per customer depending on what type of business they did). If they do no business you get nothing. Chase here in New York has 2 types of part time hours (generally speaking) 20 hours and 24 hours. Unlike working in retail or fast food, and ive done both, your hours are pretty much guaranteed.
