Seeing that a public institution requires three years of security work experience, what is the security work experience, specifically those jobs?

The so-called security is to be a security guard for three years.

The main duties of security guards are as follows

Responsible for the reception of visitors. The work in the mailroom. Like express delivery, these

Responsible for the company's safety work and emergency handling.

Be responsible for the entry and exit management of company personnel.

Fourth, be responsible for regularly patrolling the company to check the abnormal situation.

Fifth, the management of employee discipline.

Some companies are also responsible for fire safety inspection.

I hope this helps,
