What is the difference between public institutions (tourism bureau) and civil servants? Is it easy to be promoted?

In contrast to enterprise units, public institutions are generally institutions set up by the state with a certain public welfare nature, but they do not belong to government agencies and do not have state rights. They are not for profit, but only for profit. Affiliated institutions of some countries, such as research institutes, hospitals, public schools, public institutions, etc. Generally speaking, there are full wages (like civil servants, the state finances the allocation), like schools; differential wages (the state and your own unit each have one percentage point to distribute wages), like hospitals; and independent public institutions, which do not have funding from the state but have Established business unit. Benefits are generally slightly lower than those for civil servants. However, some public institutions with high autonomy also have high wages and benefits (such as electricity).

Civil servants have an administrative establishment, are supported by state finances, and perform the functions of managing the country, all three of which are indispensable.

As you said, the tourism bureau is a public institution. As for whether it is a management unit with reference to the Civil Service Law (it varies from place to place, it is between civil servants and public institutions. The treatment is the same as that of civil servants, but the establishment is different). In the administrative district where you are located, there are too many uncertain factors when it comes to promotion, but what is certain is that judging from the current situation, there is no need to think about fair promotion.
