Evaluation of organisational culture dimensions and their change due to the pandemic.

The purpose of this research is to determine whether the Covid-19 pandemic has had an impact on the change of organisational culture in public high schools. Additionally, if there has been a change in organisational culture, to what extent does this change differ from the preferred type? Cameron and Quinn's OCAI questionnaire was used to determine the types of organisational culture. 453 valid responses were obtained from teachers of randomly selected public secondary schools in all regions of the Czech Republic. Pre-Covid-19, the present and preferred status were assessed. It was found that initially hierarchy culture was predominant, while currently preferences for adhocracy and market culture have increased significantly, although the hierarchy type still prevails. In the type of future, respondents will see the clan of organisational culture. The shift in each type, but also in each of its dimensions in the three periods studied, provides the researcher with a theme for deeper research into the context, and for school institutions and principals to develop strategies to support the creation of a healthy organisational culture.
