How much should an insurance agency pay commission splits with their licensed agent?

I have been working as a service agent for 2 years with a small firm, only on small and medium group sales and service. I am a licensed FL health, life, and annuity agent. Recently, I attended a sales conference for individual health sales and got very motivated. I brought all the information back to my boss and she was resistant to change and worried that the additional business would hurt our flailing small group clients.

I thought about becoming independent and pursuing leads on my own, as I have the setup for a home business and have previously worked for myself with some success. I am quite sure she picked up on this vibe from me and tentatively asked me to work individual leads on my own time and she would split the commissions with me 65/35 (my part being the lesser). She was adamant that no time during my regular PT week could be spent servicing these new leads.

I did some online searches and from what I have found, this is not a favorable agreement.

I am curious if other insurance agents (in the health and life arena) have similar or better splits with their agency to help me determine what the proper proposal (rebuttal) should be for this arrangement.
