Theoretically, the company has no right to interfere in your personal privacy, as long as it does not involve national security or other people's privacy and does not slander the company's corporate reputation. Others have no right to interfere.

But if your company has this requirement, if you don't do it, you probably don't have to do it.

Do I have to log in to private QQ at work? In principle, the company has the right to limit the working hours of employees.

It is unreasonable for you to use personal QQ during working hours. If the company doesn't prohibit it, it's part of your job.

So you log in to your QQ during working hours, which is equivalent to work, and this company can control it.

You can apply for job QQ, and don't confuse it with personal QQ. Use work QQ during working hours.

Now it's a two-way choice. The company chooses you, and you choose the company. If you feel that the company's approach is not what you want, you can choose to go to another company.
