Corporate Social Responsibility

We support the local communities in which we operate. One of the concrete actions we take is to organise a full in-house day at our office together with the IMC Weekendschool initiative in Rotterdam South. The IMC Weekendschoool organisation aims to provide children between 10-14 years old with a platform to learn about what the World has to offer in terms of companies and jobs. The kids can voluntarily join and go on excursions on Sunday. Usually these kids are from lesser developed backgrounds that do not prepare them too well for the working future. By organising these excursions IMC aims to let them discover all opportunities that are ‘out there’ for them.
