Traditionally, the apprentices and trainees organise a Christmas sale themselves at the SIEGENIA-AUBI KG head offices for the staff. The proceeds from this - which are topped up by the management - go to beneficiaries nominated by the employees. In 2014, the apprentices and trainees presentated a donation to the Achenbach Christian Community e.V. in Siegen, for the "Heidenberg Girls Club". The Heidenberg Girls Club is involved with girls between the ages of 6 and 13 at Heidenberg in Siegen. Every Friday, girls have the opportunity to spend a couple of hours there doing a range of activities, such as cooking and handicrafts. Not only do the staff supervise these activities, but they also give the girls the chance to talk about any problems they may be facing and help them to find solutions.
