The cruelest part of the workplace development process is that while you understand the cruelty of these rules through all the experiences you go through, you still have to choose to adapt to it.
Strictly speaking, entering the workplace is the only way to really enter the society, not only to deal with work tasks, but also to deal with all kinds of interpersonal relationships.
In the workplace, no matter how good the relationship is, it seems fragile in front of interests. Two people who can't wear a pair of pants can fight for their own interests. So the saying "the workplace is like a battlefield" is absolutely true.
