The subject of the research is organizational culture in schools. The aim is to find out its potential change after the pandemic. The respondents are randomly selected secondary school teachers from all over the Czech Republic. Cameron and Quinn's OCAI questionnaire is used to assess the type of organizational culture. The types of organizational culture before Covid-19, currently and preferred are identified. It is found that initially the culture of hierarchy prevailed. Now the market and adhocracy culture has grown significantly. The preferred type is clearly the clan. At the same time, the shifts of each dimension of each type in all three situations studied are identified. The identified shifts can help school managers adopt strategies for creating and promoting a healthy organizational culture.
