Anonymous group research carried out at companies is important and principal because it points out deficiencies in the company culture, possibilities for further company development, and it secures more trust from employees. We have focused on the priorities within the value hierarchy of the employees at a company which produces structures from reinforced concrete. The cohort of employees underwent two rounds of anonymous testing. The Test of Colour Semantic Differential (TCSD) was used for the purposes of the study. The results are not to be applied generally as every company has its individual needs.
