our company and served as input for the human resources agenda for the coming years.
Following on from the survey, in January 2020, Boskalis was recognized by Effectory, a leading provider of employee engagement solutions, as a World-class Workplace. This award is made to companies based on their employee survey score. Boskalis scored higher than the global benchmark average. Onboarding As an extension of our professionalized recruitment process we renewed the group onboarding process. Interactive guides were developed to give new hires and managers more guidance during the critical first months. The traditional introduction day was also redesigned with more focus on interaction and establishing a strong sense of pride. Internal mobility A key theme that emerged from our employee survey and strategic human resources plan was a shortage of clear career development opportunities within Boskalis. We have taken a number of steps this year to enhance the work that we do to facilitate our employees to reach their full potential within Boskalis. Together, these measures have succeeded in driving up retention to 91% at our head office.
The overall results of the engagement survey showed that employees feel a great deal of pride in the company and passion for their work. It also identified several areas where Boskalis can improve, including providing more clarity on career paths and opportunities inside the company and sharing more information about Boskalis strategy, activities and projects with employees across the business. We also learned that many employees find sustainability important; they wish to contribute their part and be kept informed on what the company is doing with regards to sustainability. Steps have already been taken to respond to the survey including launching a new internal communications platform for improved information sharing and the introduction of several new and improved tools and approaches for career development. In addition, in 2020 we will intensify the communications around the updated sustainability strategy internally as an important cornerstone of the new corporate business plan.
The great sense of passion and pride in our company is reflected in an e-NPS of 18,5 which is ahead of peers in the industry.
