Individuals apply for supplementary endowment insurance.

It is the legal responsibility and obligation of the company to provide social security for employees who sign labor contracts, which is necessary. If the company really wants to insure you, there should be no such application. Is it because the company has ulterior motives? If you really want to write, the general format should be like this:

Application form/application

* * Company:

I am an employee of a certain department of the company. I joined the work in * * month. I am willing to work actively, can abide by the company's labor chronicle, and can complete the work task well. I asked the company to apply for social endowment insurance for me to solve my worries.

Applicant: * *

Date: ...

You'd better fully understand the real purpose of the company asking you to write an application, and then enrich it into this application. Personal views are for reference only.
