Social: Practicing Corporate and Social Responsibility

Practicing social commitment together for the good of the community: financial and personal support is important, indeed often existential, for people in need and for humanitarian organizations. We are aware of our social responsibility and actively serve the community. On a regional level, we support schools, charitable institutions, and aid organizations. In addition, our climate certificates also help support international projects that improve living conditions for people around the world.

“Retarus Helps”

We combine continuous corporate growth with long-term social commitment under the motto of “Retarus helps”. In doing so, we financially support a number of different social projects in various regions. Employees are also given two days’ leave each year to get personally involved in “their” project on a voluntary basis.

Health and Well-Being

As an employer we aim to provide long-term job security, the best working conditions, and personal development options.

Retarus places great importance on balancing work and family: flexible working hours, honor system-based working hours, part-time work, unbureaucratic time off to care for children and relatives. Ensuring a healthy life and promoting well-being at all ages are essential for sustainable development. In addition to state-of-the-art ergonomic office equipment, Retarus offers corporate fitness activities and even individual training sessions with its own, in-house fitness and health trainer. Employees can schedule an exam with a company physician, who also offers regular vaccinations.

Diversity

Retarus employs people from all over the world, regardless of their gender or age, belonging to different cultures, religions, and ethnic or social groups, and embraces the diverse skills and experiences they bring along. Retarus thrives on this diversity as an invaluable source of talent, creativity, and experience. We are sure that our employee diversity helps us to better understand our markets, which in turn ensures the long-term success of our business.

Education

High-quality education is the basis for sustainable development. In Germany, Retarus is one of the avant-garde companies when it comes to training: Ever since the job profiles “IT Specialist for System Integration”, “IT Specialist for Application Development”, and “IT Systems Management Assistant” came to be, Retarus has been providing training in these professions and, in many cases, hires graduates from these areas for permanent positions. In cooperation with private universities, Retarus offers the option to complete a dual bachelor’s or master’s degree in several courses of study. Retarus pays all tuition fees for students and offers further career opportunities after successful completion and graduation.

Training and educating our staff is a fundamental part of our corporate success. Retarus employees can take advantage of a wide range of internal and external training options, such as language courses, sales training programs, certifications, and communication or presentation courses. Retarus supports its employees when it comes to external training courses by offering flexible working hours and vacations as well as funding for extra-occupational studies.

Retarus’ commitment is not limited to its own employees. The company regularly donates computers to schools in the poorest regions of the world. In 2022, for example, Retarus donated to two elementary schools, École élémentaire Popenguine II and École élémentaire Amandaye Popenguine, in Senegal. This is one way Retarus pursues the goal of ensuring greater educational equity worldwide. Employees of the Retarus-sponsored wind project in Gurajat, India, are offered annual training courses. In addition, 405 school children have been given access to education there to date.

Governance: Sustainable Corporate Governance
and Corporate Respon­sibility

Retarus’ Business Model Is Focused on Sustainability

Founded in 1992 by Martin Hager and owner-managed ever since, the company is growing organically, without venture capital or third-party investments. We strive for trust-based and long-term customer and partner relationships, some of which have existed for as many as 30 years.

Responsible Corporate Governance

In its Code of Conduct, Retarus has committed to conducting business in an ethical, legally compliant, and socially responsible manner. Retarus pledges to provide a safe and ethical working environment for all employees and ensure that they are treated with respect and dignity.

Sustainable Supply Chains

Retarus has also established a binding policy for the ethical, social, and legal conduct of suppliers, consultants, manufacturers, contractors, partners, and other third parties as well as their employees, agents, and other representatives (“Suppliers”) in a Supplier Code of Conduct (“SCOC”). This SCOC defines — as a supplement to applicable laws, ordinances, regulations, and policies — the minimum standards expected of all suppliers. Suppliers must apply these minimum standards to their supply chains, particularly to subcontractors and sub-suppliers, in clear terms. In addition, we also encourage suppliers to strive to comply with international and industry best practices.

Certifications

Retarus is audited for compliance with ISAE 3402 / SSAE 18 / SOC 1 and reviewed for compliance with ISAE 3000 / SSAE 18 / SOC 2. These standards certify the reliability, availability, and process integrity of the company’s solutions as well as the reliability and effectiveness of its internal control system. Furthermore, Retarus has successfully completed the DIN EN ISO/IEC 27001:2017 certification process covering the development and operation of the Retarus services in Munich and the data center at the same site. A corresponding information security management system protects the confidentiality, integrity, and availability of information by applying a risk management process. It also provides interested parties with the assurance that risks are being managed appropriately.

Resilient Communications Infrastructure

With the continuous development of its Enterprise Cloud, Retarus contributes to the expansion of a global, resilient communications infrastructure that promotes sustainable industrialization, is innovative, and supports companies in implementing innovative processes.
