The employment relationship is a contractual one whether or not a contract of employment was signed. Contracts can be express or implied contracts, i.e., you agree to work and I agree to pay you. Verbal bargains are nearly always upheld as long as those implied contracts are governed by particular employment standards and obligations established by the common law.
