Both California contract law and tort law allow for legal action when a third party wrongfully interferes with a contract or ongoing business relationship. California courts have long recognized causes of action for tortious interference with contract and tortious interference with prospective economic advantage.When an individual other than an employer intentionally interferes with another individual's employment relationship, and causes them to lose their job. A cause of action exists for negligent interference with another's prospective business advantage if the defendant acts unreasonably and wrongfully. Wrongful or tortious interference with contracts happens when a thirdparty intentionally causes a contracting party to commit a breach of contract.
