First, check the agreement. The majority of contracts will include a provision that stipulates when and how the parties can be released. It’s important the clause is followed closely to ensure neither is in breach of contract (which can result in a legal mess). Additionally, if the contract allows either party to end the working arrangement, it will most likely include a clause that specifies the number of days’ notice that must be provided to the other party. If there was no written contract and termination was never discussed orally, the best course of action is for both parties to get together and come to an agreeable conclusion.
