This study examines the association between corporate concentration and labour conditions in Hungary's cereal industry from 2003 to 2022, focusing on key labour-related variables. Using data extracted from a Stata database, the analysis was conducted through IBM SPSS 26, applying bivariate correlation tests to assess the relationship between corporate concentration and seven labour condition variables, including wages, working hours, and employment conditions. The results show a significant positive correlation between corporate concentration and gross monthly earnings, monthly wage, overtime, and basic hourly wage. Results suggest that increased market dominance is associated with enhanced financial compensation. However, its association with the number of full-time employees, the age of active workers, and paid holidays remains statistically insignificant, indicating a weaker link to broader employment conditions. It is important to note that these findings, based on correlation analysis, indicate association and do not imply causality. These findings underscore the dual relationship of corporate concentration, revealing how economic benefits can coincide with potential labour market challenges, potentially reshaping employment dynamics and trade union influence.
