In a bid to give back to the local community and the less privileged, the Grenex team embarked on a donation drive of sanitary wear and food items to a shelter housing victims of domestic violence including human trafficking on Mandela Day in Capital Park, Pretoria. The donation did not only promote health and hygiene but also restored a sense of dignity and empowerment to the women. It demonstrated Grenex’s support to the community and compassion, which the team perceived as crucial for the victims’ healing and reintegration into society. The team also prepared and served lunch to the residents of the shelter that afternoon.
