Collaboration starts with the simple willingness of a person or organization to help others and make a change by doing so. You never doubted in case nobody get’s back to you ?
In fact … the real question is “what do they get from me if they do ?”
Don’t rely on others to get back to you for support … be pro-active and experience the reaction and appreciation of being a team player and partner in business.
Supporting each other is not a question of organizational hierarchie, position or function … it is about personal attitude and professional thinking.
