Most of us taught in school that we have to get a decent job right after the graduation.
Unfortunately, the school forgot to teach certain people to be decent, not to be a complaining b*tch and manipulative.

Most managers(There are good managers too, is just I am mentioning the bad ones) in my country are heartless, manipulative, inconsiderate and irrational.

The only good about these kind of managers are consistencies. Consistently being a KAREN in the workspace b*tching about everything and everyone.
