Is it reasonable for training institutions to pay half of social security?

It is unreasonable for training institutions to pay half of social security, because the unit did not buy five insurances and one gold for employees. This kind of behavior is illegal and will be fined. According to the provisions of Article 86 of the Labor Contract Law of People's Republic of China (PRC), if the employer fails to pay social insurance premiums in full and on time, the social insurance premium collection agency shall order it to pay within a time limit or make up for it, and from the date of default, an overdue fine of 5/10000 shall be added daily; Failing to pay within the time limit, the relevant administrative departments shall impose a fine of more than one time and less than three times the amount owed. When there is a social security dispute between employees and their units, they may apply for mediation, arbitration and bring a lawsuit according to law. For enterprises that refuse to pay five insurances and one gold, employees can complain to the social security bureau, the labor inspection brigade and other relevant departments.
