The early childhood education teacher workforce is consistently relied upon to bolster children's academic and socioemotional development in preparation for kindergarten and long-term outcomes. This is especially true of children who, historically overlooked and marginalized, are labeled "at risk." While research has focused on pervasive stressors as obstacles to these classroom professionals (e.g., teacher/teaching stress, curricular mandates, quality assessments, COVID-19), there is less research on stress in relation to the formation of teacher identity; specifically, how stress contributes to and detracts from the formation of a teacher's micro-identity, and how negative impacts of stress to the micro-identity may contribute to teachers' decisions to leave the field. Although once considered to be one of the fastest growing industries, The Great Resignation, as it has come to be known, estimates up to 25-30% of the workforce leave annually. To better understand the choices teachers make to leave the profession, the current study examined the influence of stress on teachers' microidentity by centering the voices of six Head Start teachers. Implementing a qualitative design, this investigation asked (a) Who are the Head Start teachers in the workforce today? (b) What are the particular stressors with which they contend? (c) How does the micro-identity of these teachers change as a result of stress, and what are the potential choices that follow? Results and findings indicated that Head Start teachers experience (1) stress as reality, (2) stress-shaped identities, and (3) identity-mediated choice. Implications and insights are discussed.
