Administering Teenagers perceived Parents’ Job Insecurity Questionnaires and Subject Well-Being Questionnaires to the sample consisting of 281 teenagers, the paper is to explore the characteristics of teenagers’ perceived parents’ job insecurity and its effects on subject well-being. The results showed that: As the average score of the students in the high school and the university were both higher than the overall average, the one of the middle school students was lower. Additionally, the perceived qualitative job insecurity of fathers of the teenagers in the university was significantly higher than that of the high school and the middle school. Also, qualitative job insecurity of fathers was significant positive predictor of teenagers’ negative emotion, however, job insecurity of mothers showed no significance to teenagers’ emotion. Thus, there are two main conclusions: teenagers in the university worry about parents’ loss of jobs more often than others in the middle and high school. Secondly, it is the qualitative job insecurity of father that causes negative effects to teenagers’ subjective well-being while the effects from the job insecurity of mother is not obvious. The combination of job insecurity and subject well-being of teenagers is effective for human resource management and teenagers’ mental health.
