Background: One of the most task-relevant attributes in contemporary business environments relates to effective time management. Time management is directly related to employees' psychological impacts; it influences work-related aspects such as stress, employee turnover, well-being, job satisfaction, and job performance. Purpose of the study:The study determines the psychological impacts of time management on employees within a sector high in time demand and dependent on pre-set deadlines -event management, which is an under-examined business sector.Design/methodology/approach: An explanatory, deductive research approach was selected where an existing theoretical framework was applied to a sector high in time demand. The study used a quantitative approach -using a self-administered questionnaire representing the different dimensions identified in the time management environment (TiME) measurement scale -to collect data from 151 respondents in South Africa (RSA). Hierarchical regression analyses were performed to measure psychological impacts on employees based on their time management practices Findings: Positive and negative psychological impacts were experienced based on the dimensions on the TiME scale. Positive psychological experiences resulted from the avoidance of procrastination, setting of deadlines, sufficient supervisory and procedural support, and sound time allocation. However, the tendency to focus on only one task could negatively influence the psychological impacts.Recommendations/value: The cost of employees experiencing negative psychological impacts is high and could lead to stress, procrastination, and demotivation. This could lead to loss of productivity, missed deadlines, and loss of contracts. To prevent these negative impacts, organisations could add policy recommendations to implement effective time management daily.
