Sioen is a stock quoted company with family roots and traditions. We are creating a stimulating working climate in which those who want can develop their capacities to the full.

Family is at the heart of everything we do ever since our creation. This reflects in our company values. They are the set of behaviours that we expect all our stakeholders to embrace in order to realise our ambitions for our business, our people and our communities.

The Sioen values are very straightforward. They are what we stand for, what we believe in and esteem the most important in business and in life in general. They determine our priorities and are the measures to our success.

Although we are stock quoted, we have very strong family roots and traditions. We capitalise on the advantages and have evolved in the course of 3 generations into a strong and reliable growth company.

Advantages include:

We operate in a spirit of "everything is possible". A “that’s not in my job description” is simply unheard of at Sioen. Family members, management and the Sioen personnel in general is very 'hands-on'. We are willing to take on tasks outside of formal jobs in order to ensure the success of the company.

Equal opportunities

Women play an important role at management level, especially as the wife and three daughters of company founder Jean-Jacques Sioen hold top management positions. Worldwide, the number of women employed in the company is increasing every year.

We are committed to providing an enjoyable, satisfactory working environment without discrimination and with equal opportunities for every coworker. The policy of equal treatment and opportunities applies in, but is not limited to employment, training, promotion and compensation. We do not tolerate any sexual or sex-based harassment or exclusion in the workplace.

Long-term outlook

We think years, decades ahead instead of going for hitting goals this instance. This visionary and patient attitude allows good strategy and decision-making.

Open communication

Sioen has always practiced open communication. This keeps us in tune with people’s wishes, aspirations and needs. Vacancies are filled internally wherever possible. Employees are encouraged to train further. The Sioen style is direct and clear, and as such is appreciated by customers and employees alike. This allows new ideas to be implemented quickly and efficiently and contributes incontrovertibly to innovation.

Through our various works councils we try to communicate openly and in a spirit of confidence with personnel representatives. Consultation meetings and additional discussions are held when major topics come up.

Our level company structure makes it easier to listen to people, and we quickly hear new ideas, initiatives or grievances.
