PurposeBullying affects at least one-third of the workers through either direct exposure or witnessing, both of which lead to compromised health, and as a result, reduced organizational effectiveness or productivity. However, there is very little evidence that organisations provide effective protection from bullying, and in fact, the converse appears to the case. The purpose of this paper to explore the role of both individual and organisational power in the creation and maintenance of the problem. Such an approach moves away from the specific practice of identifying “bullying” that typically engages targets and perpetrators in a dance that is really just around the edges (Sullivan, 2008) of a larger problem; a culture that permits the abuse of power and ill-treatment of workers, in both practices and through organisational politics.Design/methodology/approachThis paper elucidates key problems with organisational response as identified in the literature and critically examines weak organisational response to workplace bullying using the power theory, arguing that while overt approaches to addressing bullying appear to be underpinned by a simplistic, functionalist understanding of power, practices on the ground are better explained by more sophisticated “second-dimension” theorists.FindingsThere is a need for organisations to move beyond the current individualistic understanding of bullying towards a more nuanced understanding of how anti-bullying policies and procedures are themselves an exercise in institutional power protecting and reinforcing dominant power structures.Research limitations/implicationsThe literature from which this paper is drawn is limited to studies published in English.Practical implicationsThe authors advocate a realistic assessment of the role of both individual and organisational power in the creation and maintenance of workplace bullying, as a way forward to plan appropriate intervention.Social implicationsWorkplace bullying is problematic for organisations at several levels, and therefore for society.Originality/valueThat power is relevant to workplace bullying has been apparent since the work of Brodsky in 1976 and Einarsen's early work, this paper builds on a the more nuanced work of McKay (2014), D'Cruz and Noronha (2009), Liefooghe and MacDavey's (2010) and Hutchinson et al. (2010), exploring the organisational response to the raising of bullying issues by individual employees as an exercise of power.

Graduate students who fulfill teaching roles in the undergraduate laboratory play an important role in establishing a positive learning environment. A host of various graduate teacher training programmes have been developed, implemented and evaluated accordingly in order to enhance their teaching capability. In addition research has also documented the varied or sometimes complex factors that influence graduate students' teaching capability. This present study set out to explore graduate students' sense of psychological empowerment as an influencing factor on their perceived teaching self-image and behaviours. The Teaching as a Chemistry Laboratory Graduate Teaching Assistant (TCL-GTA) programme was developed to enhance the sense of psychological empowerment experienced by seven chemistry graduate students at an Irish University as a means of enhancing their perceived teaching self-image and behaviours. The data collected throughout this study involved both qualitative and quantitative forms through conducting interviews and administering questionnaires. The findings of this research suggest that the level of psychological empowerment experienced by graduate students lends considerable and positive contributions to their perceived teaching self-image and behaviours which are influenced by a number of contextual, training and personal factors. This research should interest those involved in teaching chemistry in higher education as well as those interested in empowerment of either teachers or postgraduate students undertaking teaching duties.

Throughout countries such as Ireland, the U.K., and Australia, graduate students who fulfill teaching roles in the undergraduate laboratory are often referred to as "laboratory demonstrators". The laboratory demonstrator (LD) model of graduate teaching is similar to the more commonly known graduate teaching assistant (GTA) model that is prevalent in the United States. While the responsibilities of LDs and GTAs in the undergraduate laboratory are similar, both cohorts experience different recruitment and training processes that can influence their teaching behaviors. With respect to enhancing the teaching capability of GTAs, considerable research has investigated the design, implementation, and evaluation of various GTA teacher development programs as well as identified various factors that influence their teaching behaviors. However, there has been relatively less research devoted to enhancing the teaching capability of LDs. This research study set out to inform the design of a teacher development program for graduate students who fulfill LD roles. This study involved the collection of both quantitative and qualitative data as a means of comparing LDs (N = 28) and undergraduate students' (N = 224) perceptions of LDs' responsibilities in addressing cognitive, affective, and psychomotor learning experiences in the noninquiry general chemistry laboratory. In catering to the misalignment of perceived LD responsibilities, this research offers faculty the evidence−align−develop framework that can inform the design of a teacher development program for LDs. Given the similarities between LDs and GTAs with respect to their status as graduate students, their relative experience in learning chemistry, as well as their role in the laboratory, this framework can also inform the design of GTA teacher development programs.

Designing and evaluating teacher development programs for graduate teaching assistants (GTAs) who teach in the laboratory is a prominent feature of chemistry education research. However, few studies have investigated the impact of a GTA teacher development program on the verbal interactions between participating GTAs and students in the undergraduate laboratory. Further, little research has been devoted to the development of an instructional model designed specifically for GTAs. This research set out to develop an instructional model to underpin a GTA teacher development program and to evaluate its impact on the cognitive and psychomotor verbal interactions between GTAs and students in the laboratory. Seven GTAs participated in the Teaching as a Chemistry Laboratory Graduate Teaching Assistant (TCL-GTA) program that featured the development and implementation of the Meaningf ul Learning in the Laboratory (MLL) instructional model seeking to nurture undergraduate students' cognitive, psychomotor, and affective domains of learning. The verbal interactions between each GTA and the students they interacted with were audio recorded for the entire duration of general chemistry laboratory sessions that took place before, during, and after the TCL-GTA program. The purpose of this article is to explore the influence of the TCL-GTA program on the cognitive and psychomotor verbal interactions between GTAs and undergraduate students during general chemistry laboratory sessions.
