"Working With Each Other and For Each Other" - Teamwork @ Hölscher

mehr erfahren

Everyone knows his role in the team, is able to make independent decisions and take on responsibility – towards himself, other teammates and the company. We promote transparency by means of active dialogue, even in difficult situations. 



Loyalty and sincerity towards oneself and the team are the keyfigures for honest teamwork. Transparent communication and targeted feedback based on honest assessments are a matter of principle for us and are formulated appropriately.  
We do not talk about each other, but with each other.



Our personal commitment to performance reflects our demand for the highest quality. Achieving set goals increases team performance as well as overall team satisfaction. Each of us contribute to the appreciation of performance through words of recognition.


Respectful and polite behaviour with each other is characterized by appreciative communication. We show this by being interested in opinions and open to personal actions of our colleagues. We treat each other with respect, regardless of position, age or gender.



We trust each other and know we can rely on each other. We stand up for our actions and demonstrate this through open communication with each other. 



Adherence to deadlines and agreements as well as conscientious working methods are binding components of functioning teamwork. We are attentive partners in discussion, open to presenting not only our strengths but also our weaknesses and actively contribute to the team.
