How will the unit handle the long-term improper relationship between the leaders of Chongqing PICC Property & Casualty Co., Ltd. and female employees?

If this leader is your husband, then threaten him and say that you will go to his superior. Generally, such people are very afraid of losing their reputation and will be more honest.

If your wife is a female employee of this unit, then tell her to go to her parents' house to make trouble. Women are generally more afraid of embarrassment and love face. Or just change her company, the insurance company is not a good company

Of course, all this is based on you still want to fulfill the family.

How can the unit handle this? How can any leader handle this kind of thing? Unless something goes too far and causes a commotion

It is best to be controlled by the leadership of the higher-level unit. This needs to be petitioned.

If you don’t want to continue living, I suggest you catch the adulterer and obtain evidence, or upload it to the Internet and use the pressure of public opinion to ruin the reputation of the couple.
