The datet contains .m4a files that are recordings of conducted interviews and .docx files that contain transcriptions of conversations. The recordings are 10 individual interviews, and 2 focus group interviews with 4 participants each. All participants are teaching professional with at least two years experience in secondary vocational education. 

A list with topics and themes for the individual interviews acted as basis for the individual interviews and framework for reference during these conversations. The areas included are background information on the participant; articulation of tacit knowledge and expertise; interaction and sharing with colleagues; status; power; interdependence; trust and psychological safety; and risks. Background information was discussed to initiate the interview, create a context for the conversation, and to be able to allocate and contextualise information and quotations in the Results chapter. The other areas were derived from the literature review. First, interaction and sharing with colleagues were discussed in a more general sense to allow the participant to share their point of view freely. After, topics about status, power and safety were approached more directly to interrogate more closely issues identified in the literature and to gather richer data in these specific areas. 

Insights from the individual interviews served to depict themes for the focus group interviews. These insights came from simple notes made during the individual interviews, from transcribing, and from a first, brief analysis. The themes that appeared to be needing more data on were Communication and formulation of knowledge; Facilitation (that is, facilitation of sharing and interaction by the organisation); and Appreciation of colleagues / Influence of character. In general, questions during the focus group interviews were asked to confirm or contradict preliminary findings and to elicit more personal views and stories relating to the issues discussed.

The dataset cannot be reused or accessed by other parties to protect anonymity of participants. Participants speak freely and openly about their professional identity and modus operandi, with that discussing and at times criticising direct colleagues, management, and other parties. Making this data public / reusable would put their professional and interpersonal position at risk, which would not be ethical. In .docx files, participants´ actual names have been replaced by other names to protect anonymity. In recordings, participants´ actual names may, and their real voices can be heard.
