In the unit, I was retaliated for reflecting material problems, but I was asked by the company to give gifts. I refused, didn't I?

The boss's father-in-law retaliated for material problems. Maybe your report violated his interests, usually economic interests. The boss asks you to apologize, which shows that they are the unity of interests and you are a just person. The boss only asks you to apologize without criticizing you, which shows that he also values you, but because they are the unity of interests, they can only make you bow your head. Besides, you must be very wronged. Only in this case will you feel that the rich are bullying you. In fact, when you work for a long time, you will have a different view from another angle. I have experienced this incident of yours, because I am also an upright person.
