As introduced on the previous page, there is a tendency for regular employees and part-time workers to be discriminated in terms of basic salary. It's weird that there is a difference in salary for the same job. But how, until now, there was no law to crack down on the irrational difference.
Therefore, what is introduced in this reform is the "prohibition of unreasonable differences in treatment." The Ministry of Health, Labor and Welfare has stated as follows.

It is forbidden to make unreasonable differences in the treatment of basic wages and bonuses between regular and part-time workers and fixed-term workers in the same company.

The following pages provide an easy-to-understand explanation of what kind of treatment difference is irrational according to the guidelines provided by the Ministry of Health, Labor and Welfare.

Check the irrational difference criteria

For example, is there such a time? In this way, if you ask your employer for an explanation, but the explanation is not returned, or if the explanation is returned but ambiguous, you can not say a complaint.
The reforms will allow part-time and fixed-term workers to ask employers to explain the difference in treatment from regular employees. Employers will also have to respond to demands for explanations. This eliminates the event as in the example above.

Until now, the ADR by the government was provided only for short-term workers (excluding the law on equal treatment), but fixed-term workers and temporary workers were not provided.
