In real life, using pseudonyms is a common phenomenon, especially in some workplaces, such as working in small factories. This behavior may be due to the following psychological reasons:

1. Privacy protection: Using aliases can protect personal privacy and prevent personal information from being abused or leaked.

2. Adapt to the environment: In some specific workplaces, using pseudonyms can help individuals better adapt to the environment and establish better relationships with colleagues.

3. Avoid troubles: In some workplaces involving sensitive topics or complicated interpersonal relationships, using aliases can help individuals avoid unnecessary troubles.

It should be noted that using pseudonyms may also bring some negative effects, such as trust problems or misunderstandings. Therefore, when using aliases, it is necessary to carefully weigh the pros and cons to ensure that the rights and interests of others will not be infringed or adversely affected.
