This qualitative single case study examined the social and emotional needs of teachers and what they need from principals to nurture the use of effective social and emotional competencies. Individual interviews were conducted with secondary teachers from one school district in Indiana. Three themes emerged. Teachers need: (1) boundaries, (2) space and time, and (3) collaboration and connectedness. In addition, this study explored what principals could do to nurture the social and emotional needs of teachers. Six findings were reported: Principals should (1) have a clear understanding of SEL competencies (2) nurture unique opportunities for collaboration (3) nurture a variety of topics on which to collaborate with teachers (4) provide the space and time necessary for teachers to process (5) model work-life balance (6) nurture personal connections between adults within the school. These findings will help principals develop their leadership skills in supporting teachers in their application of social and emotional learning competencies.
