I didn't get a health certificate, so people from the health department came to check it as soon as possible and issued a fine of 1000 yuan! ! I find it unreasonable. Can I complain to them?

In some industries, employees must hold health certificates, such as catering industry. But the object of punishment should be the employer. If your friend works in it, it is unreasonable for the employer not to tell him to apply for a health certificate, or for the employer not to apply for a health certificate or to ask for a new one, and the employer bears the responsibility and the Health Bureau punishes you. You can file an administrative reconsideration.
