After employees leave their jobs, how can personal information bound at work be exempted from the company agreement?

Both parties can sign the resignation disclaimer.

The format of the resignation disclaimer is as follows. The employee's resignation and activities have nothing to do with the original company. Someone officially resigned in a certain month. Since this month, someone has no employment or labor relationship with our company, and any business behavior he is engaged in has nothing to do with our company. If you find that others are engaged in related business and consulting activities in our name, please contact our company as soon as possible.
