What a Korean Company's Warning Letter to a Former Employee Looks Like

Got a warning letter from your old Korean employer? Here is what these letters usually say.

 


Some of you have asked me what to do when a former employer sends a serious-looking letter by registered mail. In Korea, this is often "content-certified mail," where the post office keeps a record of exactly what the letter said. It becomes useful evidence later, which is why companies like to use it.

The book gives a sample, and it is worth knowing how these letters are built. The company's representative director writes to the former employee. The tone is polite but firm. The letter says the company is disappointed that the person moved to a rival company, and that it is writing to prevent any possible claim for damage.

Then it reminds the employee of what he signed. In the sample, there was an employment contract from August 1997 with an agreement not to move to a rival company. There was also a contract signed on July 20, 2007, before he left, about keeping company secrets and confidential information.

The letter then states the warning. If the employee uses trade secrets from the old company, it would be a severe violation of the contracts and of the law, and the company would be obligated to take civil and criminal action for damages. A copy of the relevant legal provisions is attached. The letter closes with a courteous line, "May you find happiness and success," then the date and the company representative's name.

The book recommends this letter as a preventative step. The idea is to send it in advance, rather than waiting for the rival company to take advantage of the trade secrets.

For workers, there are two things to remember. First, the letter itself is not a court order. It does not take away your right to work somewhere else. Second, it shows the company is watching, so be careful never to bring documents, files, customer lists, or technical data from your old job.
