Education of BOLTJES employees

The EDUCATION of BOLTJES EMPLOYEES project is co-financed by the European Union.

Continuous education and personal development constitute an important and integral part of our corporate culture.

The extensive “Education of BOLTJES employees” project (project number CZ.03.1.52/0.0/0.0/19_097/0012614) is underway in our company in 2020 and is co-financed by the European Union.

The subject of the project is a company-wide education programme, which ensures development of human resources in our company. A considerable number of our employees will be participating in training sessions focused on soft skills and managerial skills, as well as in accounting, economics and law courses.

We perceive the project as being the main tool for further development of our employees in the sense of improvement, enhancement and deepening of their professional competences, which will also contribute towards a higher level of performance both on the part of the staff and the company as a whole.
