The listing agreement you sign when listing your home is a binding contract with the Real Estate Agency. The agent represents the broker of record, the owner of the company. The broker "owns" the listing contract and can make the decision on whether or not to release the seller from the contract. The broker can assign another agent to handle the listing if the relationship is strained. It is not matter of the broker "allowing" the agent to release you, rather it is a business decision by the broker to keep the signed (agreed upon) listing contract in the office to sell your home. In most cases the broker has no idea that you are at odds with your agent!
If your relationship has gone bad with your current agent, speak to the broker to have another agent handle your listing -or- you can ask to be released from your listing contract. Once you have that conversation with the broker, I am sure that the issues will be resolved.
Best of luck to you! let us know how your conversation goes and the outcome!

Knowing the details would really help address your concern.
In NJ, the listing agreement a seller signs is with the Real Estate Broker the Agent represents and not the Agent. So an Agent may want to release and the Broker won't allow them.
As an Independent Brokerage we consider client relationships the most important thing we do. It is more important to us to have a satisfied customer who recommends us over and over again then to have a displeased customer just to get a commission.
The bottom line is that selling a home is one of the most stressful times a person can go through. The seller should be confident in their Agent and the Brokerage they are using.
