This should be based on your own situation. Generally, jobs in regular enterprises don't need to be guaranteed, unless you are a foreigner, you haven't provided them with anything that can prove that you have the ability to bear the corresponding responsibilities, or your academic qualifications and other aspects don't meet the requirements of the company's general recruitment, so the company wants you to provide guarantees for the safety of the company's property.

on the other hand, if the company requires all people to be guarantors and there is no appeal, then it is this requirement that the company has set for this position, which may be due to the consideration of business insurance experienced by the salesman, and there is nothing wrong with it. You can stay if you want, and you can change to another company if you don't want.
