Broker provide leads to his agents?

[Frank J.]

I joined a small office this summer and slowly realized that the broker does not do much for the office to provide any leads or new business. We have relationships with some property managers that we do rentals here and there but these listings are not exclusive so basically any office could get them. 

There are 3 agents in the office but only one agent who has been there the longest seems to get all the leads since he has been there for awhile. My broker does not really advertise anywhere to get new business and walk-ins are non existent.

I understand real estate is a business that you need excel on your own but I think I do need one needs some sort of support from the office who he pays 50% commission on deals. 

Is this normal? Im trying to get a perspective from others and see if I need to change office or not. 

Thanks
