ENThe purpose of the study is to determine what factors affect the career opportunities of employees in the organization. A quantitative survey was conducted using the Anketa.lt website. Statistical Package for Social Science (SPSS) version 24.0 was used for statistical analysis of the survey data. The data analysis was carried out using descriptive statistics, comparisons between groups (Mann-Whitney, Kruskal-Wallis, χ² tests, Z-tests) and tests for statistical relationships (Spearman). The results of the study showed that the most important factors affecting career management and career opportunities in an organisation were the pandemic, the organisation's lack of concern for employees' careers, too much competition and a lack of cooperation between the organisation and employees. Environmental uncertainty factors were found to have a greater impact on younger and less experienced employees. Remote or hybrid workers are less likely to be exposed to uncertainty factors. The results of the study show that during the Covid-19 pandemic, uncertainty was amplified and affected men more than women. Most respondents are from the business sector, so restrictions on the survey are possible. The results of the study should help organizations respond more adequately to the influence of environmental uncertainty factors on the career management of their employees. The paper analyses the uncertainty factors that influence the career management process in organisations. Keywords: career, career management, high environmental uncertainty. [From the publication]
