To investigate the effect of the working period in forestry, Cox proportional hazard model, one of the survival analyses, is applied to “Green Employment” trainees in Tochigi Prefecture. The target period is from fiscal year 2003 to 2017, and all the trainees in this period are the objects of this research. According to the models used here, workers who “are a hometown person” tend to work for longer in the forestry industry. On the other hand, “working in the forestry owners’cooperatives”, “employment age is in their 30s or 40s”, “hired through the job placement agency”, “former job is blue collar”, “the ratio of job openings to the job seekers in the month of his just starting the work”, or “the period of his starting the work” are insignificant. The fact that almost all the variables supposed significantly are insignificant implies that “job-quitting” will be caused by the environments after they enter the jobs, rather than their conditions when they enter the jobs.
