What should I do if I meet an irresponsible leader?

If you meet an irresponsible leader, you may have to take on more responsibilities. What you give will be rewarded. In such an environment, leaders may make you. You can try to avoid turning "responsibility" into "achievement", and you will gain a lot from your work and grow rapidly. You should have your own principles and don't let yourself become the kind of person you hate. Reporting should have articles of association to avoid being framed by others.
