Gap issue

According to a survey by a newspaper, 80% of Japanese workers hope to be employed as lifetime employee.
Lifetime employment (permanent employment) is a system of long-term employment in Japan. The employers hire workers once a year and retain them until their mandatory retirement age. On the other hand, employment pattern has diversified in Japan. Non-permanent employees, such as part-timers, temporaries, and dispatched workers, account for one-third of labor force population. These non-permanent workers tend to work under adverse conditions: low-paying and high risk of layoff. Subsequently a gap issue between permanent and non-permanent employees became to be recognized.
Seniority-based system is a traditional practice in the Japanese businesses. In this system, salary and promotion are determined depending on the age and length of service. Recently, the pay for performance system was partially induced in Japan; however, it was only applied to the permanent employees but not to the non-permanent workers. They gain unreasonably low wage and have little chance of promotion.
Postdocs have similar underlying issues. They work under bad conditions and have little chance of promotion. They are required to yield results, but it seems not to be correctly assessed. They should publish, but they would perish.
After all, permanent employees never give up their vested interests. They are all out to keep their status on the sacrifices of non-permanent workers. To survive, we must overcome these disparities by ourselves.
