sentence: People usually sign a contract when something important or costly is being done.
sentences_before: Sometimes, a contract is written down and signed by the people agreeing to it, but it does not always need to be.
sentences_after: For example, when people take a job, they will sometimes sign a contract with their employers. The contract will show what the person must do as part of his job, how much they will be paid, and so on. The person and the employer will sign the contract, and it will become a legal promise.
