<prompt> Human: Im still very new to financing and controlling my money and I need help in knowing where are the best places to leave my money. My sister recommended a credit union but she didnt give me any real information on what theyre good for or why its better than using a bank. Can anyone help?  <response>: Generally:Banks work for their shareholders, so are often looking for new ways to charge fees to their customers. Credit unions work for their members, so seek to provide banking services without a bunch of fees. Not all banks are bad and not all credit unions are good, just a general rule of thumb.
