Different people have different views of work. In Japan, there's also freedom of thought. However, it is best to avoid expressing your views on work to those around you after you change jobs. This is because your boss may have a different view of work than you do. As with politics, differences in values can easily lead to conflicts, and you should be cautious about topics such as your views on work because you will not have your own supporters in the company immediately after you change jobs.
