Whether a labor contract was signed before attending the training, and whether there is a description of the training period in the labor contract. There are two kinds of training, one is pre-job training, which means that training is the premise of entry. If the training is unqualified, the company has the right to refuse to hire, so this kind of training does not need to be paid. The other is induction training, which belongs to probation period. During this period, the wages of workers who also pay shall not be lower than 80% of the minimum wage of the same position in the unit or the wage agreed in the labor contract, and shall not be lower than the minimum wage standard where the employer is located. However, if the employee leaves the company during the probation period, the employer needs to be notified 3 days in advance.
