Dear Ms. Kwitowska. Thanks for your question. The CTB has not identified authors of any chapters by name? I suggest you cite it as follows:
Community Tool Box. (Retrieved on [INSERT DATE YOU ACCESSED]). Chapter 13. Orienting Ideas in Leadership, Section 6. Recognizing the Challenges of Leadership. URL: /en/table-of-contents/leadership/leadership-ideas/lead...
Feel free to tailor the above order to whatever specific reference style you are using.
