Why is signing a confidentiality agreement essential ?
It is essential to sign an agreement on confidentiality when doing business in Thailand for several reasons:
Employee Obligations :
Such agreements stipulate the duties of employees of the company or organization that signed the document. By signing a confidentiality agreement, the employee must agree to keep the trade secret and any information they receive confidential. The purpose is to prevent an employee from disclosing sensitive and classified information they have learned, including technological innovations, marketing, client lists, and other information.
Protection of the Interests of the Company or Organization :
A confidentiality agreement is a tool to ensure the permanent confidentiality of any information considered essential to maintaining the competitive edge of the company or organization. This is especially true today when the private sector is massive, and many organizations in the same area compete with each other. If an employee gives significant parameters about the technology or customer base of their company to a competing organization, they will be able to get ahead without making as much effort.
Legal Provisions :
The act of signing a confidentiality agreement on the part of Thailand’s employees obliges them to comply with the legal requirements of the country, such as adherence to the Trade Secrets Act in Thailand. This act contains legal provisions that do not allow sensitive company information to be disclosed.
Avenues for Taking Action :
