Contract negotiation is the negotiation to realize a certain transaction and make it reach a contract. The so-called contract must have the most basic "elements", namely "target, cost and time limit for a project". Once these elements are agreed, the contract negotiation will be "basically" concluded. A quasi-contract is a contract with preconditions. These preconditions refer to the conditions that determine the establishment of contract elements, such as licensing, raising foreign exchange, waiting for lawyers to review or waiting for the printing and formal signing of official texts. From the perspective of natural relationship, quasi-contract is the predecessor of contract, with exactly the same content and format, except that one is herbal medicine and the other is original; But legally speaking, there are essential differences between the two. The quasi-contract can automatically become invalid when the preconditions are lost, and it will not bear any liability for compensation; But the contract must be executed, otherwise it is a "breach of contract"

Generally speaking, the unit should sign a labor contract with you within one month of the employee's employment. It is illegal to sign the contract after more than one month. From the second day after the employee joins the company for one month to the day before the renewal of the labor contract, the unit shall pay double wages for extortion. If the date of the first day of employment is added after signing the labor contract, it means that the unit has avoided the risk. Once signed, the unit can prove that the unit has not violated the law and the workers cannot defend their rights. If the laborer puts forward rights protection before signing the labor contract (the contract has not been signed for more than one month), then as long as he can provide relevant evidence of labor relationship with the unit, he can protect rights.
