With the increasing casualisation of the teacher labour force, there is little written on the experiences of casual teachers and the challenges they face in brokering professional identities within constantly shifting and uncertain work contexts. Being a category bound casual teacher (a product of category boundary work) is a complex subject position. The aim of this article is to advance our understandings of the identity work inherent in casual relief teachers (CRTs) performativity. Anti-essentialist theories support this exploration of CRT subjectivities and processes of discourse appropriation. Using collective biography methodology as restoried memory work, this article speaks back to neoliberal politics of casualisation. The stories draw attention to how both experienced practitioners and newly graduated teachers might 'do' category boundary work within the complexity of school politics as they navigate the uncertainty of gaining and maintaining employment in the Education market.

It is the norm for the casual teaching precariat to experience insecure labour conditions requiring an additional skill set to teachers with stable employment. As more beginning teachers than ever before commence work in casual employment-often a tenuous and unsupported transition into the profession-it is beholden on teacher educators to re-think aspects of their preparation. Four teacher educators undertook 'memory work' based on their previous experiences as casual teachers. Content analysis of follow up focus group discussions stressed the emotional and challenging nature of casual teaching, for both novice and experienced teachers. Findings from this small study, as well as previous research on casual beginning teachers and casual teachers, provide significant insights that have ramifications for initial teacher education, highlighting the importance of the emotional practices of teachers.

Planning for learning is essential for creating environments conducive to deep learning and to developing student understandings. Standard 3 of the Australian Professional Standards for Teachers (APST) (Australian Institute for Teaching and School Leadership [AITSL]. 2014) specifies the need for all graduate teachers to be able to 'plan for and implement effective teaching and learning'. Quality planning involves the systematic use of feedback data to design activities that encourage the assimilation and synthesis of information, leading to the creation of new understandings. Student learning should always be the goal.

Produced through market relations of neoliberal managerialism, teacher subjectivities are becoming progressively commodified. With the increasing casualisation of the teaching workforce, the well-being and status of casual relief teachers (CRTs) can be seen as an area of concern, at risk of 'flexploitation'. More than just a convenient labour pool, CRTs operate on the margins of school communities, a space fraught with a range of issues. In many instances, CRTs experience less job satisfaction; less rapport with students and colleagues and less access to school information, professional development, resources and teaching materials. This article draws on a positioning theory to frame the discursive production of CRT selves within the neoliberal milieu. It offers a detailed analysis of collective biographies that explore narrative formations of casual teaching. Schooling discourse is replete with metaphorical language that frames teacher positioning, and a range of existing metaphors in CRT literature highlight their vulnerability in particular. Rather than offering an analysis that addresses casual teacher performance as a problem to be solved, this article proposes that the relationship between 'structural marginalisation and the 'othering' that CRTs can experience is associated with the politics of market-related performativity.
