What, if any, are your responsibilities to the broker

[Bill Morris]

My wife is contemplating getting her license primarily to use for our own investments. However, she will likely also do some work on the side as a Realtor as time permits. I'm wondering what are the typical responsibilities/requirements that a broker might have or do they vary wildly? Do you need to put in time at the office answering phones, showing properties etc? Or, can you simply hang your shingle with a broker and work as much, or as little, as you'd like?

Thanks in advance for any feedback.
