Among the various public transportations, the best way to keep the driving schedule is by far the subway and other trains. Unlike buses and taxis that are affected by road conditions, subways run on dedicated routes, so the timetable and actual operation time will not be significantly changed. 지하철 지연증명서 발급
However, no matter how crowded the subway is, the situation changes during rush hour. There is a slight delay in the process of getting on and off because it is so crowded. Sometimes the door or screen door breaks down. The older the route, the more frequent these breakdowns are. jasminevista.com
If you’re on your way home from work, you’ll end up late or a little late for your appointment, but if you’re on your way to work, things are different. It’s a relief that it ends up being a little bit scolded by your boss for being late, but in the worst case, you may be disadvantaged in the personnel evaluation. 
Fortunately, most companies avoid being late if they submit documents that prove subway delays. A “delay certificate” is used in such cases. If you submit a certificate of delay, you can avoid disadvantages by recognizing normal reasons for being late in various situations.
Basically, a delay certificate can be simply issued by requesting the station office at the subway station. However, during the already crowded commute hours, office workers who want to obtain a delay certificate may flock to the station office. No matter how considerable it is to wait for a delay certificate when you are already late, you will be impatient.
In this case, it is better not to wait in the station office, but to get a ‘simple delay certificate’ issued on the Internet once you go to work. A simple delay certificate can be issued on the website that operates each subway line. However, depending on the region and operator, the Internet issuance service for a simple delay certificate is not provided. As a result of confirmation, the metropolitan subway and Daejeon urban railway were able to be issued on the Internet.

One thing to note is that a ‘simple delay certificate’ is literally just a ‘simple delay certificate’. As anyone can easily obtain it, it does not prove the use of the train or the damage caused by delayed operation. A simple delay certificate is sufficient to admit the reason for being late, but in some cases, a written delay certificate with the user’s name and station manager stamp may be required. It is necessary to check with the submitter in advance whether a simple delay certificate is sufficient for the purpose of submitting.
